Does personality leave the body when we die or does our personality live on. This would presume that "personality" is a thing - a noun.If it is a thing, where does it go?

If personality isn't a "thing", where do we get it?  Are we born with it or is it a learned thing from the people around us? If God says"everything is good", when, then do we become hateful, selfish, loving, serene etc?

What are your thoughts?
