Hate is, of course, an emotion. Emotions arise as a result of external conditions or as a result of mental machinations.
Emotions are often precursors of certain behaviors.
Actors are expert in consciously manipulating their emotions thus enabling them to act as if they were actually experiencing some external circumstance. Adroit liars are always good actors. This might explain the predominance of jews in the Hollywood bailiwick. One does not necessarily allow his emotions to govern his behavior and often that very emotion undergoes a metamorphoses during the expression of itself. One might perhaps hate another to the point of killing him.
