SPOILER: the plot thickens in ep.s 4 & 5
Seriously, this is a spoiler for episodes 4 & 5, do not read if you have not seen it.
The group after many years sees some new people, who follow them home, and seems to want to be helpful, but their leader Charlie turns out to be a psycho. He wins some affection and confidence by helping to drill a well for the group, but as he rises in status, his poisonous personality is exposed as he assaults Evie.
The setup for this plot twist seems fake. Why would Charlie go out of his way to show he is a criminal who wants to take over the group and abuse everyone, and why would he be so confident that the group would do nothing in response? So, taking that for granted the group talks over what to do about it.
The regretfully unanimously decide Charlie must die. Ish goes out to talk to him ... stupidly armed with a hammer, but backed up by the group with guns. Charlie torments and provokes him more - and Ish kills Charlie by beating him to death, which no one hears or finds out about until the next morning.
My question was, subsequently Ish has conflicts with his conscience that shows up over and over again, he has questions or doubts about executing Charlie who has committed crimes and as much said he is not going to leave and that he will take over the group and do the same thing to Ish's wife.
Do the writers overdo it on the second-guessing and remorse or doubt that Ish has. I try to put myself in that situation and it is frontier justice, it had to be done for the benefit of everyone. If I had had to kill Charlie, after all of the threats he spewed, I would not worry about it for a minute after that. I don't know that I would have even gone down and tried to talk to him, and in fact it might have been necessary to remove the threat from all of the other men in that group. In primal situations seems like you cannot waffle about right and wrong. Probably why in the American West, at least in the movies people are so carefully polite to each other - if one cannot show respect, they deserve to be watched carefully.
So, why do TV and movie writers dwell on this so much?
