Donald Trump is completely obsessed with revenge. How do we know that? Because he has talked about revenge and retribution repeatedly himself.
In 2013 he tweeted “Always get even. When you are in business, you need to get even with people who screw you.’ – Think Big.” In 2014 he tweeted this quote: “‘Revenge is sweet and not fattening.’ – Alfred Hitchcock.”
In 2011, he gave a talk with a list of things they don’t teach in business school. The first thing on his list was this:
Get even with people. If they screw you, screw them back 10 times as hard. I really believe it.
