The motivation for the gentiles is to emulate their Jewish overlords, gain their favor, and thusly keep their place in the decadent elite. The degenerate elite like being able to rape, murder, extort, etc. without consequence and the protection of the kike buddies is the only thing keeping that around.

Not to mention that the vast majority are sociopaths or sadists or some other form of antisocial cunt who gets off on the pain and suffering of those they perceive as being under their control and lesser.
