I read a story about Trump's childhood.
"In elementary school, Donny impressed classmates with his athleticism, shenanigans and refusal to acknowledge mistakes, even one so trivial as misidentifying a popular professional wrestler. No matter his pals’ ridicule, one recalled, he doubled down, insisting wrestler Antonino Rocca’s name was “Rocky Antonino.”
At the military academy where he attended high school, Donny grew taller, more muscular and tougher. Struck with a broomstick during a fight, he tried to push a fellow cadet out a second-floor window, only to be thwarted when two other students intervened."
He was never not the narcissist he is. If a time traveler came to kill anyone, he would have always have assumed it was for him. Narcissists are always the center of their own universe.
