No man. In that hypothetical, you would have had a civil war on your hands with Trump as a martyr.

All of his devout cultists would have gone out to actually just murder every "lib". If you think his cult is a terrorist organisation now, you can't imagine how bad it would've been with him dead.

Murdering the figurehead of a violent movement doesn't dissipate the impetus, it causes it to explode in every direction.

Look up the murder of Jorge Eliecer Gaitán, or Inukai Tsuyoshi, hell even Archduke Franz Ferdinand.

The death of an evil figurehead is not always the best path forward, because ideally we would want to avoid generalised death, destruction and bloodshed as much as possible.
