"Tch, don't waste your time trying to figure it out." It's not something he needs this guy pondering over. A pacifist is a boring person, in Bakugo's opinion. Mostly because a lot of them end up fighting anyways.

"I don't have a reason to fight you." Just in case this guy's having second thoughts about sticking around. Bakugo's violent and aggressive, but he won't blow energy on a wuss. It's pointless.
