EGO - The part of you that defines itself as a personality,
separates itself from the outside world, and considers
itself (you) a separate entity from the rest of nature
and the cosmos. Perhaps necessary for survival in
some evolutionary bygone, in modern time it
leads only to (albeit often disguised) misanthropic
beliefs and delusion.
In short ... "I"
Ego is responsible for hate, fear and delusion.
