Good and Evil are subjective, as much as we decive ourselves they are not.
Survival in itself is amoral. It lies above morality, since to be a moral judge you first need to survive.
What is a life worth? Whose life? The answer may be worthless and priceless, both at the same time. Entire books have been written on the subject, but in the context of the game, the problem with "evil" is how it is written. The writers often approach the situation thinking "what the most evil thing I can I can do? What evil option can I add here?"
Instead they should be adding sensible options, since all action, weather they are perceived as evil of good, follow a logic of their own and make sense within their own framework.
People you might label "evil2 do not think they are evil. Their actions makes perfect moral/logical sense to them. In fact, they might consider you evil.
This is nuance that is often lost in writing.
