I think some people don’t understand that if quantum suicide works it wont prevent the gun from being fired: that doesn’t kill you; it wont prevent the bullet from hitting your head: that doesn’t kill you; it wont prevent the bullet from inflicting massive brain damage as long as certain information survives.
If “quantum immortality” really were a thing, its effect would not be to save you from subjective death after deciding to commit suicide, but to prevent you from deciding to do so, or from landing on a path wherein you’d decide to do so, in the first place. That’s where all the measure is.
All the measure is only there later though. Until after the bullet hits your head, the worlds in which you shot the gun have similar measure as the worlds in which you didn’t.
