Karma...is it real? Please help me?

Honestly, no one knows. but if it dose exist its treated me with respect. I've always been a realy nice guy to just about everyone. An example is this one guy was blaming **** that was happening to him that he was blaming me for when i had nothing to do with it and he got many people to believe him too. But a month after that, he was arrested, put on drug charges, put into a psych ward in a hospital, suicide watch, expelled, and lost a lot of his friends when they found out he was making **** up about me.
