Answer 1

I think that's a psychopath.

Answer 2

He sounds like a "Bull in a China shop"...

Insensitive!

Answer 3

He is probably a sociopath. That could be the product of his environment or he may have some type of biological disorder. I guess he could be the product of evolution. Those personality characteristics you use to describe him  would allow a person to increase the chances of the species surviving and spreading that gene. So that could be something hereditary that have gotten worse through time.

Answer 4

I say neither he is a product of his social upbringing. It will all fall on his head so if you associate with this person they will drag you down also, get a new friend.
