While proportionality is generally expected, it is not an absolute rule, and a person is not morally compelled to suffer a serious injury simply because the threat they face is unintentional.

“I don't know if I would say that a person is necessarily supposed to bear a serious injury if it could be prevented even with lethal self-defense against somebody else. I don't know if they would have a moral compulsion to bear that serious injury.”

Self-defense actions should be proportional to the level of threat, and it is categorically disproportionate to use lethal force against someone who is only going to unintentionally cause non-lethal h

“If you know someone is going to unintentionally harm you but in a non-lethal way to use lethal force against them is just categorically disproportionate and I I I I think pretty clear.”
