I am an atheist and also believe that the universe is completely random. Even the (known) laws of physics don't explain or control what happens at the subatomic level. What does this have to do with the OP's post? "Bad" people take advantage of every opportunity to do whatever they want (power, control, money) without conscience or empathy for others. Only their own agendas. I don't think there's anything like Karma, God or some other universal system of justice. Someone cited Hitler as getting his comeuppance because he ended up killing himself. So his suicide balanced the millions of people he killed? I don't think so.
