I'm sorry but did the people who's telling the ml is a red flag knew that this story is set in apocalyptic world where everbody do EVERYTHING to survive so they all agreed to the rules. People are the one who ALL VOTED (except the protagonist) agreeing to the death. The ml just implemented the rule that was set because his the leader. In this case the protagonist was just wasn't aware on how shitty the world became. He haven't even experienced what its like to kill a zombie. He still have the moral and ethics he had when the world was ordinary and safe. So I get why he acted like that
