I certainly don't want to see the President assassinated. I remember seeing "The Parallax View" years ago. Trump's allies would find some way to blame it on some poor hapless progressive who was at the wrong place at the wrong time. We don't want to make a martyr out of him. When I think of the holy saints and martyrs, including our modern day martyrs MLK, RFK, JFK, Archishop Romero, and others, it would dishonor them to include Trump in their principled midst.
Trump is 73 and his health habits are abominable (like most of the information he allows to be released, I am sure the medical reports about him are false). But his parents lived long lives, and who knows, they may have eaten cheeseburgers in bed, too. His mother died at 88 and his father died at 93.
I do think the only way our world will be safe from Trump will be if he dies. Even if he loses the next election he will start a TV station that will make Fox News look unbiased. He will use his demagoguery to incite his followers, and the violent ones around him, the KKK, Alt Right, militia, etc. will perform even more acts of domestic terrorism.
But all we can pray for is that his myriad bad eating habits, anger management issues, past promiscuity, etc. will be rewarded by karma and that our world will become a safer place.
