Well he loves to hate if that's a separate emotion,
Is self love an emotion he does have that , but most of his emotions revolve around hate.
He loves other haters like Putin and other dictators put he seems to really hate people who are morally good, like John McCain because frankly he can never measure up to them ,because he is morally bankrupt. He simple in his emotions and lets them rule him instead of using his brain to figure things out to me that means he's stupid. Anyone ruled by emotions instead of logical thought is a person who should never be a leader of anything. They are incapable of making the right choice in an emergency which in the end will only make things worse. Like Trump does on a daily basis he make the wrong choice in most situation .
