I know, which is why I said Tony likely wouldn't be able to do it. Nevertheless, you should be able to do so, provided you're strong enough to wear the gauntlet without it actively killing you. Captain Marvel would possibly be able to, looking at her strength in Endgame
We've already been over why Carol isn't reliably tanking a completed gauntlet usage.
It certainly isn't worth it to risk her by trying.
They'd be essentially giving them 2 options: 1) Stay there and sacrifice themselves, leaving their friends and family behind. 2) Come with them leaving their friends and family behind, but immediately rejoining them after the sacrifice. They die in both timelines either way, but in option 2 one of the Morgans has a father to raise her
That isn't how any of this works.
If Tony leaves his timeline behind, his Morgan dies when Thanos wins (because they need him to win), and he has to live with that knowledge while living with a Pepper and Morgan that know he's not their Tony because Pepper would've already seen hers die in front of her. Nobody would fucking want that. Neither party. At all.
This is a stupid idea. No sane person would agree to it when they'd be leaving something/someone behind. Period.
It's a pretty reasonable assumption to make. Thanos had the knowledge of the location of every infinity stone, he also had Ronan collecting stones for him logically he would've told him where to find them. Even if Thanos didn't tell him anything he already had an army of his own and that combined with the Power stone would've been enough even with the Avengers, considering they had a hard enough time with the Chittari. Not to mention if Ronan even touched the ground it would be all over anyway
Ronan only knew where the Power Stone was. Thanos wouldn't have shared the location of any others with him. He was biding his time to collect the rest.
And Thanos never learns the Soul stone's location if not for Gamora, which you'd know if you paid attention in Infinity War, which I suspect you didn't.
Good or bad they screwed up history just by being there, but by interacting with the past their actions rippled outward in any number of unforeseen ways altering those timelines forever. At least that's what happens according to the writers. Either way I'm done arguing about it
*shrug*
That's not screwing up history. They appeared. Doing so sets those timelines on slightly different paths. It's inevitable. Torturing themselves on how every single one of their actions might've effected events down the line is meaningless for the same reason it's dumb for any of us to do so now. You can never know. They had a job to do to save their own timeline, and they left the rest in good enough shape to be saved themselves.
That's the most they could do. This is a stupid thing to get hung up on.
