KARMA ... real or not?

Nobody wishes Karma was real more than myself. I know you and I can point to anecdotal stories where it appears Karma is in action. But let me ask you a question:

Was Abe Lincoln, JFK, Ghandi and MLKjr. assassinated?

Was Stalin, Mao, Hitler and the Kim family assassinated?

Four of the most righteous (okay JFK wasn't) and 4 of the most evil. If Karma is real, why isn't it going after Evil?

The answer: Because it isn't real.

Does that make me happy? No, it makes me angry and sad. But just because I want something to be true, doesn't make it true.
