Well, self defence and protection of loved ones is the obvious one.

Then goes the spectrum. Suppose someone is taking your property, can you employ violence to protect it? What if there is 1% risk of death to the thief? What if its 10%?

That's an excellent question, I'd say that's the kind of assessment that most likely needs to be made in the moment.

I'd prefer the people whose job it is to make those assessments on a daily basis to have a strong moral and ethical framework, and to have the psychological and institutional support to maintain a connection with their humanity.
