For some reason we really like separating things, as in "this is right, this is wrong", "heaven / hell", "jew / christian / musilm" etc... I wonder what that need comes from.

Order.

Plain and simple. Humanity's need to order, stabilize, classify, understand everything. And like they said in my Logic class...

We abstract away from reality to understand it, because its complexity is too high.

I do believe these things have their place, because without order things would be wildly insane and crazy (sometimes positive, sometimes negative), but... when with separation comes hatred and boundaries, that's when I think it is highly harmful.
