I get feelings about pacifists I have to suppress. You can say that there are people aligned closely enough to you that dying is not actually an existential threat in the same sense as your country or species getting destroyed is, but it's not a good precedent to let them roll you over without a reasonable application of force. I would personally start questioning it if I had to kill over a thousand people to save myself, but if I'm mostly avoiding collateral damage (i.e. I mostly avoid killing non-rioters/non-attackers), I would keep going. Give them a couple kilodeaths and the riot will stop.
I never said I would, I would probably be killed by a couple, at least without a lot of support. Look at the Black Hawk Down incident for what killing a thousand people requires. That actually failed because the Americans left, they should have stayed even if it required killing a thousand more.
