We all know the story by now about when he stuck a firework in a sleeping homeless man’s mouth. Fireworks back then packed a bigger punch than they do now. M80’s used to be like a smaller stick of dynamite. How likely is it that he killed that homeless guy?
He came out later and said he wasn’t the one that did it, his friend did, he just happened to be there and didn’t do anything about it. Even if it happened, I doubt it killed him. Ot probably wasn’t some large firework either. Homeless people are the most resilient people on the planet. They can survive an apocalypse unfortunately.
