basic principals: Selflessness versus Selfishness.

Well done on this post!!
The above statement, however, is not entirely true.
A person who advances himself and achieves his goals is acting in his
own self interest. This is not evil. Not unless he is hurting someone else
in order to do it. Therefore, I'd have to say that good and evil are not
implicity tied to selfishness and selfness. In fact, some of the most evil
acts I can think of lie at the extreme edge of altruism.
Evil depends on whether the act does harm to oneself or someone else.
