Even I, personally, would be very upset that the president of the United States was assassinated. But, that the particular president of the United States that was assassinated was Donald Trump, I would, personally, celebrate, probably, for several months.
I honestly think he is suffering from severe dementia, so yeah I’d kind of feel bad. Yes, he’s a horrible man, but no more so than any current member of Congress or tech billionaire encouraging him.
They are the real problem, and unfortunately even Trump falls into the “devil you know” classification. It would be a gamble whether or not we get a worse situation with a more capable person who has the same power and motives. It’s the time traveler’s dilemma of getting rid of Hitler and finding out the future is now worse because of who took his place.
