What are we to make of Trump boasting about telling lies?

Link “I just argued with the PM of Canada that the U.S. has a trade deficit with Canada. I didn’t have a clue. Turns out I was wrong. Ha, ha, ha.”

What are we to conclude? Is Trump immoral, or could it be that he is amoral? How does he expect people to react to his statement? Is he a complete moron? I am at a loss for how to respond.
