Some of Jesus' lessons.

Many people feel that they can determine what is right or wrong by following their heart—their desires and passions. However, the Bible says that “the heart is more treacherous than anything else and is desperate.” (Jeremiah 17:9) If our heart is not guided by God’s wisdom, it will lead us to act in a way that we will later regret.—Proverbs 28:26; Ecclesiastes 10:2.

Proverbs 28:26:

Whoever trusts in his own heart is stupid,
But the one who walks in wisdom will escape.

Ecclesiastes 10:2:

The heart of the wise one leads him in the right way,* [Lit., “is at his right hand.”] but the heart of the stupid one leads him in the wrong way.* [Lit., “is at his left hand.”]

The Bible contains the truth about God and how he wants us to behave. (1 Corinthians 6:9-11; Galatians 5:19-23) He desires that people come to know this truth. (1 Timothy 2:3, 4)

Many people who do not want to listen to the Bible’s moral standards look for religious teachers who will “tell them what they want to hear.” (2 Timothy 4:3, footnote) Yet, God’s Word contains this sobering warning: “Woe to those who say that good is bad and bad is good.” (Isaiah 5:20) Clearly, God will hold accountable religious leaders who do not accurately teach people what God says is right and wrong.

Do the Bible’s moral values condone intolerance?

No. Those who want to please God follow the example and teachings of Jesus Christ. He taught his followers not to judge others but instead to show love and respect for all.—Matthew 5:43, 44; 7:1.

Those who follow Jesus were to uphold God’s moral standards in their personal life. However, they were to accept the fact that other people may choose to follow different beliefs. (Matthew 10:14) Jesus did not authorize his followers to use politics or any other means to force God’s views on others.—John 17:14, 16; 18:36.

Who has the authority to set the standards of right and wrong? That question was raised at the very beginning of human history. According to the Bible book of Genesis, God designated a tree that was growing in the garden of Eden as “the tree of the knowledge of good and bad.” (Genesis 2:9) God instructed the first human pair not to eat the fruit from this tree. However, God’s enemy, Satan the Devil, suggested that if they ate from this tree, their eyes were “bound to be opened” and they were “bound to be like God, knowing good and bad.”​—Genesis 2:16, 17; 3:1, 5; Revelation 12:9.

Adam and Eve faced a decision​—should they accept God’s standards of good and bad or should they follow their own? (Genesis 3:6) They chose to disobey God and to eat from the tree. What did this simple act imply? By refusing to respect the limits placed on them by God, they asserted that they and their offspring would be better off setting their own standards of right and wrong. How successful has mankind been in attempting to exercise this godlike power?

After reviewing the teachings of prominent thinkers throughout the centuries, the Encyclopædia Britannica states that from the time of Greek philosopher Socrates to the 20th century, there have been “repeated debates over just what goodness and the standard of right and wrong might be.”

For example, the Sophists were a prominent group of Greek teachers in the fifth century B.C.E. They taught that standards of right and wrong were determined by popular opinion. Said one such teacher: “Whatever things seem just and fine to each city, are just and fine for that city, so long as it thinks them so.” By this measure, a person living in Nazi Germany in the 1930's could be under the mistaken impression that it's right (“just and fine”) to despise Jews and spit at them, or even assault them on the street. Since the majority in their community, or “city,” would likely engage in that behaviour or attitude towards Jews.

Popular opinion is an unreliable guide. For example, if you had lived in a society where the majority believed that child sacrifices were acceptable, as some societies in the past have thought, would that have made the practice right? (2 Kings 16:3) What if you had been born into a society that viewed cannibalism as a virtuous act? Would that have meant that eating human flesh was not really wrong? The popularity of a practice does not make it right. Long ago, the Bible warned against that trap, saying: “You must not follow after the crowd for evil ends.”​—Exodus 23:2.

Jesus Christ identified another reason for being cautious of adopting popular opinion as a guide to right and wrong. He exposed Satan as “the ruler of the world.” (John 14:30; Luke 4:6) Satan uses his position to mislead “the entire inhabited earth.” (Revelation 12:9) Therefore, if you set your standards of right and wrong purely by what is popular, you might be adopting Satan’s view of morality, and that would obviously be disastrous.

Should each individual, then, decide for himself what is right and what is wrong? The Bible says: “Do not lean upon your own understanding.” (Proverbs 3:5) Why not? Because all humans have inherited a fundamental flaw that can warp their judgment. When Adam and Eve rebelled against God, they adopted the standards of the selfish traitor Satan and chose him as their spiritual father. They then passed on to their offspring a family trait​—a treacherous heart with the ability to recognize what is right but with the tendency to pursue what is wrong.​—Genesis 6:5; Romans 5:12; 7:21-24.

The Encyclopædia Britannica, in discussing ethics, observes: “It does not seem surprising if people know what they ought morally to do but then proceed to do what is in their own interests instead. How to provide such people with reasons for doing what is right has been a major problem for Western ethics.” The Bible correctly puts it this way (as mentioned before): “The heart is more treacherous than anything else and is desperate. Who can know it?” (Jeremiah 17:9) Would you trust someone who is known for being both treacherous and desperate?

Granted, even those who have no belief in God have the ability to behave in a morally upright manner and to develop practical and honorable ethical codes. Often, though, the noble principles embedded in their codes simply mirror the moral standards of the Bible. Although such individuals may deny God’s existence, their ideas demonstrate that they have an inherent potential for reflecting God’s personality. This proves that as the Bible reveals, mankind was originally created “in God’s image.” (Genesis 1:27; Acts 17:26-28) The apostle Paul says: “They are the very ones who demonstrate the matter of the law to be written in their hearts.”​—Romans 2:15.

Of course, it is one thing to know what is right; it is quite another to have the moral strength to do what is right. How does one come to have the necessary moral strength? Just as eating nutritious food gives you strength to work, reading God’s Word gives you strength to live by his standards. Jesus likened God’s utterances to life-sustaining bread. (Matthew 4:4) He also said: “My food is for me to do the will of him that sent me.” (John 4:34) Feeding on God’s word helped equip Jesus to resist temptations and to make wise decisions.​—Luke 4:1-13.

It also motivated him to teach this basic rule of how to do what is right, which became known as the golden rule: “All things, therefore, that you want men to do to you, you also must likewise do to them.” (Matthew 7:12)

It's also the responsibility of your fate. A man once pushed another man who was bothering the atmosphere at a bar and as he was getting a push he tripped, fell over, knocked his head on the board stone of the side walk and died. In what circumstances it all happened, no one was planning to kill anybody but people did die.

Who's responsible?

The one that got pushed was doing wrong.
The one that pushed didn't know what to do.
Both are responsible for the causality and how did they all end up at that place in the first place.

People get into problems because for who they are you could say.
At the bar might have been 30 people, they were all there so all are responsible.

Television might have caused millions of problems.

Education is responsible for everything.
