He would have died as a hero, not having gone back to the past in a MAGA america, in a house with a white fence ewww, with a woman who was dead, and who had moved on.I was perfectly happy with Cap's ending. It's better than the cliche Thanos kills him idea people seemed to want.
In addition, Steve's ending is one of the most hated, and has turned jokes and memes on the internet. No one is laughing at Nat and Tony, for example.
His end should be celebrated, not turned into memes, and question marks.
