I think generally nasty people end up getting what they deserve because of the way they lead their lives, if someone makes you feel like shit, the chances are they may do it to someone who returns the favour. Also,more often than not nasty people tend to have nasty habits, like heavy drinking or smoking ( not that i have anything against smokers or drinkers), and so may die of such horrible things as cancer, although i dont think anyone deserves to die that way. Same goes for good people, in that sense i suppose this good/bad karma does make sense, and thats the way i see it.
