[MCU] How did the Super Soldier Serum change Steve Rogers mentally?
gpt
I don't think it did. He always had the mental fortitude. He accepted a very small chance to help his country. He figured out the flag puzzle. He dove right into basic training when he knew it wouldn't work. He literally dove onto what he thought was a live grenade to protect others, some of whom didn't like him one bit. 

Steve was willing to die to help asshole soldiers protect America. 

Edit: All -before- the serum.
