Put simply my personal view on evil is the intent to destruct, in a negative manner - causing unnecessary pain, etc. Good on the other hand is the
intent to create in a useful and beneficial manner for others. Although there would be times for the opposite - good destroying things for the benefit
of others, whilst evil may create things to add to the pain for others (or add to the 'self' at others' expense). Perhaps evil focuses more on the
'self' whilst good may focus more on the 'other'. There would be more to it but that's how I differentiate.
My personal focus is to stay neutral with a slight slant towards good

. I also think it could be a bit dangerous saying there's no such thing as
evil and good, because moral judgement relies upon the differentiation of both. I agree, the words are manmade but for things to exist there must be
opposites, eg day / night, strong / weak, etc. Theory of Yin / Yang. A perfect balance of Yin / Yang is Wu-Chi but that's a story for another day.
Upon the subject of necromancy - I have no idea, I have not delved nor studied the art you are talking about, with the exception of playing computer
games such as Diablo 2 which does indeed summon skeletons, golems and resurrects corpses as faithful bidding minions! Muhahahaha.
