I think it's unreasonable to expect a victim to assume that the assailant won't harm them. Moreover, the victim has a right to their property and safety--it's insane that we would put people in a situation where they have to choose between loss of property/safety to preserve the safety of our assailant. The assailant has all of the agency in the situation--only the assailant can choose to avert the situation--so the assailant should bear all of the responsibility for the encounter. If they're killed in their enterprise, so be it.

Many disingenuously respond to this with some variation of, "but theft doesn't deserve the death penalty!" Of course, I'm not advocating for the death penalty for thieves--defense isn't about justice or sorting out what anyone deserves, it's about preserving one's rights (including one's right to life). How we charge thieves in courts is a different matter.
