Open spoilers, right?
I can't fathom why they chose to kill Stark and leave Steve alive, it's seriously a backwards decision narrative-wise.
Steve leaves and goes to live in the past, therefore:
- Peggy's family is replaced by whatever family Steve Rogers has with her now.
- Rogers doesn't give half a shit about Bucky being brainwashed, killing Tony's parents, or any of that — given that he can now interfere. Nah. He just lives in some cabin with his wife.
- Hydra infiltrating SHIELD? Yeah, not gonna do anything about it either. Time paradoxes and all that.
Even ignoring those points, this goes against Steve's character. He is a man out of time, someone struggling to adjust to the modern era. He does not yearn for a better life for himself, but rather for a better world. Are you telling me that after all these years with the Avengers he never grew as a character? His most profound desire was to go back in time and dance with Peggy? What about Bucky? Sam? What about
anything he's been doing the past decade or so.
