In lot of stories heroes or protagonists will usually try to be reasonable to people not involved with the villainy, like quest givers in game that can be quite pushy or marvel civilians being dick and the heroes just having to bear with it because reasonably it's not worth fighting over it. Like in civil war a guy smack human torch in the back of the head with a bottle and I'm not even sure if they mention he went to jail and the superheroes see it as "johnny shouldn't have vip treatment in a club he frequent so that's what he get for line cutting"

I want examples of protagonists so hot blooded they will escalate stuff. Like Breckinridge Elkins, a dumb mountain man with little patience when faced with misunderstandings:

I ordered whiskey and when I had drank a few fingers of the rottenest muck I believe I ever tasted, I give it up in disgust and throwed the dollar on the bar which I had found, and was starting out when the barkeeper hollered:

"Hey!"

I turned around and said courteously: "Don't you yell at me like that, you bat-eared buzzard! What you want?"

"This here dollar ain't no good!" he said, banging it on the bar.

"Well, neither is your whiskey," I snarled, because I was getting mad. "So that makes us even!"

I am a long-suffering man but it looked like everybody in Grizzly Claw was out to gyp the stranger in their midst.

"You can't run no blazer over me!" he hollered. "You gimme a real dollar, or else--"

He ducked down behind the bar and come up with a shotgun so I taken it away from him and bent the barrel double across my knee and throwed it after him as he run out the back door hollering help, murder.

The cowpuncher had picked up the dollar and bit on it, and then he looked at me very sharp, and said: "Where did you get this?"

"I found it, if it's any of your dern business," I snapped, because I was mad. Saying no more I strode out the door, and the minute I hit the street somebody let bam! at me from behind a rain-barrel across the street and shot my hat off. So I slammed a bullet back through the barrel and the feller hollered and fell out in the open yelling blue murder. It was the feller which called hisself the sheriff and he was drilled through the hind laig. I noticed a lot of heads sticking up over window sills and around doors, so I roared: "Let that be a warnin' to you Grizzly Claw coyotes! I'm Breckinridge Elkins from Bear Creek up in the Humbolts, and I shoot better in my sleep than most men does wide awake!"
