I love this. True story, in my life, it's my step dad who keeps 3 kinds of bullets in his robe pocket. The rubber "get out" bullet, the "I'm warning you" and the "you're dead"... I also found a pistol in the cupboard once.
This is exactly why Steve provides a different point of view about the accords vs Tony's. Steve has done things because he was commanded to. It's not like he ever wanted to. You can't tell me that he doesn't regret participating in WWII. Tony has the freedom to choose because of the sacrifices Steve and his fellow soldiers made. The accords take away the freedom to choose... And Tony could never possibly understand the price Steve and his men paid to survive the war.
