I don't know how much of why he fought the results were about finances more than they are just pathological.
The guy hates losing.... if you would ask him point blank, he's never "lost" a thing in his life. So it's not at all surprising (especially with the benefit of hindsight) that he would go to great lengths, including putting public officials and normal people in harms way, to execute whatever plan he felt necessary to claim victory.
I won't speculate on specifics, people do that a lot and it bothers me, but there's something seriously broken upstairs with Trump. Just not a good human being.
