This is the best theory I’ve read so far. Granted, this season the show has been less that realistic, but being realistic that makes sense. I see a lot of comments in this sub where people fail to put themselves in the character’s place. For example, being obtuse as to why someone would be stressed out over large needles going into their gut. :-). I think this situation is another one. People just don’t kill people and have the experience roll off of them.
