Normally when this is asked, people think about reviving, curing, resurrecting. This question is about who you save if you were transported to a time a little before their death, like maybe a day before or even a week before. Anything about terminal illnesses or diseases contracted don’t really count here because, when those things happen, they happen and there’s really nothing you could do to have prevented it.
I think I would’ve wanted to prevent JFK’s assassination. I’d tell him “dude, do not get in that limo and drive down Elm Street” and I’d show him a newspaper clip of the day of his assassination. I’d probably be looked at a little crazily and suspected of maybe being involved in something that pertains to that day. But, it’s an effort I would’ve gone through to do that.


The guy who almost killed Hitler.
What if we prevented Hitler from killing himself just so that he could go on trial and shown to the world hope much of a nut job he was? Maybe that would have helped diminish the mythos that racist bigots today see him? It would be more of a saving to torture him deal for sure
fornsworth did you use a giant laser to kill him.
