Because of human nature and the nature of life, human life requires value production for oneself and others. The reward for value production is happiness. Parasitic losers are value destroyers and value usurpers. These losers are unhappy and are envious of the producers and achievers. Their resentment causes them to want to make producers and achievers as miserable as possible.
There are 4 types of value destroyers:
1) instigators (actual users of force and fraud)
2) sympathizers
3) collaborators
4) informants
