Yes, love this show! I was really surprised at the scene with Sam and the old guy. But honestly, there was no right choice there and I think she's being too hard on herself. She didn't actually know Sam all that long and yes while he may feel and think it's still not exactly the same as being human. The old guy may be a stranger but he may have a wife, children, grandkids, etc. He even seemed to feel fear more than Sam in that moment. Their lives really aren't exactly the same as humans so her choice is understandable to me. I don't think it should diminish all of her hard work on their behalf.
