I think Donald Trump evolved this way not by conscious thought and desire to be the way he is.
No, I think it is a form of "business Darwinism" and that Trump has evolved and developed these methods of speaking and using words based on winning in business negotiations. E.g. Trump evolved this way because he hates losing and loves winning. This also partially explains how Trump went from a "joke Presidential candidate" the the leading front runner and a very good chance of becoming President of the USA.
