2 part1. This ignores Moxxie who is comforting Blitz due to knowing what he is going through you know Murder family, where Moxxie didn't want to kill Martha because it would ruin the family given his past family experience, and so is Loona who asks that she wants her to kill them instead.

1. Blitz didn't want to kill them because it hit too close to home and he sees himself and his situation in them, It got to be the most obvious thing ever but yet they either missed or did not watch it which is because Sinsmas is a fantastic entire series. Go rewatch you have seen the entire series.
