Revenge is a waste of time:
It teaches people not to fuck with you
I'm not really a revenge kind of guy... but I guess there could conceivably be a situation when I would feel that way, but it'd have to be something really bad like someone I care about being murdered etc.
I don't anymore. Nobody fucks with me and I also learned to disassociate myself from the kind of people who hurt others for personal gain.
