Revenge Through Corruption

Revenge Through Corruption is a variant on Revenge by Proxy and Sins of Our Fathers. Sins of Our Fathers refers to revenge against the descendants of someone that is dead or missing. Revenge by Proxy refers to revenge by harming someone important to the living person instead of taking the option of going directly after the target of revenge. Revenge Through Corruption can overlap either trope. What distinguishes this trope is the method of revenge. Instead of inflicting physical harm, the villain attacks the mind and soul. The intent is to get revenge on an enemy by making someone important to them evil, insane, under the control of the villain, hooked on drugs, or some other comparable effect. Victims may include friends, family, sidekicks, or even distant descendants.

A person that does this would probably be The Corrupter. See Face Monster Turn and Mind Manipulation for a handy list of techniques that can be used to accomplish such an end. Compare Raised by Orcs and We Used to Be Friends. Contrast Evil Parents Want Good Kids.
