He won't live long enough. The fat POS is a walking heart attack waiting to happen...or a stroke.
Personally, I'd prefer a massive stroke with him stuck in bed for a few months staring up at the ceiling.
This scenario is even more fun:
It will be up to God to judge Trump. If everyone prays hard enough, then maybe God will give Trump a paralyzing stroke that leaves him mute, but able to move his head. He'd then spend every day looking at the ceiling and every evening watching Melania fuck any and every bodyguard she likes in the same bed with Trump’s fat, immobile body.
Finally, after several years of this, when Melania is really getting pounded doggystyle with the guard's balls dangling in Trump's face, Trump throws up, chokes on his own vomit and dies. Melania climaxes then rests and stares at Trump’s eyes as they become cloudy and slowly flatten. Finally she has the bodyguard call her lawyer.
NSFW image of the last thing Trump sees before he dies:
It's unlikely that Trump will face justice for his multiple crimes and dereliction of duty.
