When did humanity become evil?

I don't know. "Evil" is a moral construct. The things which are called evil vary from person to person. Some days I see humanity as evil (including myself) and then some days I don't. On those days, I just see it as humanity. It's not good, not bad; it just is, whether I like it or not, and who am I to judge it anyway? It depends on if I really believe in evil at that particular moment. Either way though, evil or not, it's not for me to rid the world of anything. It's only for me to rid myself of the evil I feel inside of me, and for me to evolve into a better being than I was a minute ago. "Better" meaning happier and more content with myself.
