I'm a big believer in karma - as you sow, so shall you reap. Eventually everyone will have to deal with the consequences of their actions and behaviour. It's best to walk away from a negative situation & let the law of the universe deal with it.
You're laying in your bed. You've live a long, happy life. You hear a noise. You look up and see this staring down at you in the dark. BOOM! I'd crap my Depends right there.
