Taking away bodily autonomy is very close to killing a person, yes. People value their body autonomy so much, it's such a deeply-rooted instinct that messing with it can lead to death (either straight up death or personality/ego death).

How often one hears, usually after sexual assault: "they were such a bright, chatty person before, now they're withdrawn, have panic attacks, PTSD, they hurt themselves etc." That's personality death and it comes from denying bodily autonomy.
