Wow, people are really getting too wound up with this killing thing. I hate how people think Cap is Mister Perfect who won't kill or is squeeky clean. Of course he would have to kill. What other alternatives would he have if the situation calls for it? Poeple act like he would be the Punisher. He ain't. He does it when it's neccessary. And even when it is, he isn't happy about it. Just because you have a gun it doesn't mean you enjoy killing. It says I don't want to get my ass shot, and in Cap's case. "I'm using this gun to defend myself because I'm suppose to be a symbol on the battlefield, and if I can't use my shield all the time, and if I was shot, without a firearm in a war I wouldn't be much good." What's Cap suppose to just do? Run up deflecting bullets and get from A to B untouched? He's going to have to run into Nazis at some point. And the shield won't come in handy all the time. Plus, using the shield for everything would get stale. There has to be some points where he kills. But only when he has to. Like every other soldier in war. Or a human being. Self defense. We kill someone in self defense, it doesn't mean we enjoyed it or we are a psychopath. Plus he was trained to do it. I mean he wouldn't sign up to serve his country if that didn't mean killing? It still goes when you're a symbol. When neccessary. Yes, he's a symbol of hope and America and embracing life. But if it means not getting killed in a war, this is logical. It makes perfect sense.
Put yourself in that position.
"Where's my gun?"
"You don't have one. Your shield is your weapon. You are a symbol. It's invincible."
"Just because it's invincible doesn't mean something won't happen to it. I should get a gun."
"A gun? No."
"Why not?"
"Because it contradicts everything you stand for."
"No. I'm still a symbol. Putting a gun in my hand and killing in self defense is not a contradiction. It's me deciding and making the consicience decision whether to live or die. Just because I kill, doesn't rip my symbolism apart. I still have good intentions. As long as I have guilt and I feel it's wrong makes it fine. What good's a symbol for America that's dead. Oh, and the right to bear arms is the second Ammendment in the constitution. Which is American correct?"
It dragged at the end, but you get the point.
Even if I was a super solider, I still would be scared going into battle head first ahead of everyone else with just a shield and not a fire arm.
