This is the wrong place to have a discussion about good and evil. I would go out on a limb and say most of the people here do not believe in the concept, just like they do not believe there is a right and a wrong. People are pretty much free to do whatever they like is the Trekbbs mantra.
There are just too many intelligent, well read people here to accept anything so simple as good and evil.
I'm intelligent and well read, but DO accept "good" and "evil". I just don't think they are always "simple".
But to deny them completely throws you into a dangerously morally ambiguous zone where no one can be judged and anything can be justified.
That way lies madness and destruction.
