Losing the election put him over the edge. He was always unstable but that really did him in. He actually believes that he won the election. Believing things that aren't real is one sign of insanity. They're called delusions. This man was always very vindictive and narcissistic. January 6th was all about him and trying to exact vengeance on those he believed wronged him. Anything person watching what was happening at the Capitol would have intervened and tried to stop it. Starting in November he should have cooperated with the Biden administration in the transfer of power process. He did none of that. No president has ever done that before. Organizing this event was the last straw and it was a fool's errand. He used his followers as pawns to attack the very country and its principles that he feigns affection for. I don't know what to be more despicable than that.
