Love your meta on MCU villains. It sparked some thoughts on Steve Rogers, viz. why I like the MCU version so much more than in the comics. And then it hit me. He is treated like a girl for a good part of the movie. Pre-serum Steve was insecure. People judged him unworthy based on his looks. So he changes his body. immediately after receiving the serum, he is told that he is still not good enough. He cannot be a real soldier, but he can play one on stage. Hoping you have more coherent thoughts.
