I think "evil" is a difficult concept. Deciding that X action is evil when one is not part of that action or situation and has no experience with it can be iffy. I was sure as a 20-something that I would never date a married man but I ended up marrying one (after he was divorced, of course :-) What I learned from that was to not use such extreme words unless I had been in and experienced all of a situation. "Good" and "Evil" appear more as extremes to me now, unhelpful dichotomies.

Too, ideas and ideals may change and yet we may not change with the "times"? Ten years ago the world was different but that does not make the changes (types of music, for example) "evil" just because I do not like them or my impression of them is that they are evil. What I think and feel may/may not be in line with "reality".

I think "do unto others"/karma is a good concept to practice. I want to be the best me I can be and that means when others are watching and when they are not. But whether someone else is punished or not; I know their life is "similar" to mine and the people they love get sick and die and have difficulties of their own as much/often as me and mine and/or if they are socio/psychopaths they do not feel good things as I do and I feel sorry for them. I want wholeness for myself but what that is and means to me requires knowledge of pieces and inequalities and sharp edges, etc. too.
