This was brutal to watch. But mostly because unfortunately in a time of crisis, especially with limited resources it will always be every man for themselves. That is just how humanity has been since the start of time. Yes, obviously there will be people with a conscience who wouldn't want to see someone else die, but the commune have been out in the apocalypse living and witnessing all kinds of crazy shit a lot longer than the teacher (plus we dont know his entire history pre Guwon saving him, we only got small bits and pieces and it seems he too has his own loose screws). It might be shocking to someone that hasn't had to live the full extent of those hardships to see an entire colony vote for someone's execution. It isn't right, but when the world has gone to shit and there's zombies and you have limited food and resources, normal laws and morals go out the window. It's not to excuse what happened, but it's a different perspective.

Everyone there has screws loose for a reason and they weren't forced by Guwon into voting for the man to die. We could argue that he has the power to pardon him if he wanted to because he's the leader, but then that means he could lose the "respect" of the group and be accused of betraying them and their unanimous decision. Even the megaphone guy said that it was their commune that created the law and punishment for theft.

I do feel for teacher :( it must be shocking to see the person you like do something so ruthless, especially when the father of innocent kids is involved. It was an unfair situation by regular societal standards.
