Alright, I'll explain. I don't think violence is bad against someone who's about to kill my family, because:

* I care about my family more than I care about a stranger.

* I care about people who don't kill people unprovoked more than I care about people who kill people unprovoked.

* My family are more than one person, versus the one killer.

That's why I answer no to that one.

Sure, I care about certain people more than others and I’d be willing to use violence to defend myself or my family. But that’s not the same as cheering on or advocating for an attack on someone else that may or may not have done something to harm someone totally unrelated to you.
