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.
I would travel back in time and prevent the deaths of all the other sperms in the load that became Justice John Roberts Jr. If only one of those other sperms got into that egg.
This court Jester that thinks that 12 years after civil rights and voting rights were extended to black people, that there was no racism to deal with anymore and has been trying to overturn them until he succeeded this time.
