This is sort of off topic but it reminds me of Steven Hawking saying that if aliens came to earth they would likely want to attack it and harvest the earth for resources, or whatever. Yet, Mr. Hawking has no place to speaking about an alien's psychology. In fact, I would argue that Mr. Hawking likely isn't too adept at human psychology by saying that because the closest thing he'd have to understanding alien psychology would be human psychology.
I don't think you quite got the message. It was not about how the aliens are definitely going to be bloodthirsty maniacs. It's about the downside risk, in case they actually are. Let's say there is 85% chance that aliens are rich and benevolent hippies who cruise the Universe to cure cancer and give away cases of champagne. The remaining 15% is the chance that they will be like hi-tech Texas Chainsaw Massacre type of guys. The idea is that enormous benefits of the 85% do not outweigh certain extinction of human species in the other 15%.
So if Dr. Hawking is not an expert in alien psyche, he says that whatever the percentage is, it's too damn risky to consider this. It's like playing russian roulette for $1M. A lot of people would do it, but the conservative and prudent type won't.
Okay, so now we're going to get into an argument about this? First off, your percentages are incredibly incorrect. Not only is not 85/15, there are not only those two possibilities. I know tons of people who are neither hippies nor "Texas Chainsaw Massacre" type guys. In fact, I'd say the majority of people are neither hippies nor texas chainsaw massacre type guys. But lets examine the latter:
If the Aliens were in fact Texas Chainsaw Massacre type aliens, how would they have ever evolved to the point of making it outerspace, let alone interstellar travel? It seems to me that people who are just out for blood tend to contribute nothing to the scientific community. Even further, if they are out for blood only, then they'd be stuck on their planet trying to murder the rest of their species. Their first instinct wouldn't be, "Hey, you know what, I want blood, but lets work together in order to learn physics, build space ships, find life on another planet, and kill it. I can wait that long before I satisfy this primal urge for killing that I'm having." This is ludicrous.
The fact of the matter is that it would take a great amount of work to get to a point where a race could accomplish interstellar travel. So, this eliminates the "Texas Chainsaw Massacre" type aliens because they wouldn't be able to progress beyond their primal urges to kill each other. It would also take a great amount of intellect to be able to achieve such a thing. I would argue that as intellect goes up there is also a reverse correlation to "blood thirst." I would also argue that even beginning to think about interstellar travel would require a large amount of curiousity, let alone accomplishing such a thing. As a result, this curiosity and intellect would likely mean that aliens capable of coming to Earth would be curious, and thus observational, about humankind, and unlikely to attack us. And if the aliens did need resources, I would think they'd be smart enough (as they are smart enough to accomplish interstellar travel) to get the attention of the world leaders and either barter with them or try to threaten them with war before they went into battle and probably lost some of their alien brothers in a war.
But even that is unrealistic, as it is unlikely that something smart enough to accomplish interstellar travel would be so dumb as to not have a solution for their problems at home. Even humans today are coming up with solutions to combat the environmental issues (and other issues) we are facing, and we are no where near successful interstellar travel. I can't imagine humans being stagnant in their technological growth in those areas, but booming in interstellar travel. Similarly, it doesn't make sense for aliens to encounter that problem either. Thus, that option is rather unlikely.
All in all, I'd say its incredibly unlikely that an alien race would come to earth to kill humans or pillage the earth's natural resources, because it would require an incredible amount of intellect and curiousity to accomplish such a feat. Thus, I'd put the 15% odds at 0.000000000000000000001
If you ask me, I'd say if humans found life on another planet, and had the means to get there, we'd study the aliens, not attack and kill them.
Human history is abundant with examples of opposite sort of behavior.
So your opinion here is that if humans found life on another planet, we'd try to kill it? So, let's get this straight, we'd spend billions of dollars to have our scientists go up in space ships, just to kill off life? I think you should clarify instead of responding with one sentence.
