He's a soldier. He's killed enemy soldiers.
But bandits (BANDITS) that came to kill him, and by extension his wife and foster daughters? Nah fam, "being a bandit is bad, don't do it again". BRUH! SERIOUSLY!
I'm getting sooooooooo tired of this trope. It makes sense if the MC is some rando, in a way. Despite what our resident alpha edgelords may think, it's not easy to kill a person. You go from living in Paris, 2020, never even gotten in a fist fight, to murdering bandits in your Isekai. Yeah, no.
But this is just beyond stupid.
