Evil just doesn't work. The only reason why evil people believe evil can work, is because evil can't do anything to you, but blind you. So evil people are blind. They certainly can take their BS pretty dam far, but they will eventually crush under their own lies which have them buried in sadness or garbage.
Life just doesn't want evil. Life demands life, thats why humans have gotten so far. Imagine if people didn't waste so much time with something that is never going to be profitable? Where we would be right now? What we would discover! There can be SO much to life that we havn't even tapped yet... maybe one day the world will wake up.
