[ Although at the time Tony tried to convince himself that he could just walk away from the idea of the time heist, he knows now that, even with what happened, he needed to do it. Not only because it apparently had been the only way for Thanos to no longer be a threat, for the world (universe) to be safe, but ultimately Pepper had been right. Of course she had been.

He can ensure that his daughter actually has a future that she can enjoy. It almost cost him his life, and his body will never be the same after what happened, but he wouldn't take it back. The only part that he wishes he could have changed in the whole process is avoiding scaring Pepper and his family the way that he had.
