I totally agree. I really liked Steve and I do understand that he wanted to be with Peggy and all that, but I do think it kind of destroyed his character arc and him finding his own worth without her. He had also created a family with the Avengers and with Bucky and kind of threw that all away.
I really like Tony Stark too, but I think he should stay dead.
Wanda and Vision, Bucky and Steve, Loki and Nebula
