That's a nice trip down your rabbit hole, but it is all deflection. Do you or do you not have a right to defend your life if it is actually being threatened?
In what setting?
You'll always have the instinct to defend it.
Having the "right" to defend it is an abstract idea brought upon by human cohabitation.
LOL! So, you would be unable to defend your life until society grants you that right?
No. In the same way you are able to commit murder anywhere, any time. Just a question of the consequences later.
