Everyone makes decisions in life and lives with the consequences. Your question, as it's stated now, is simply "should we have free will?"

I never made any statement about which actions should be legal. And the facile assertion that endorsing one action is either tantamount to, or requiring of, endorsement of any action that shares an arbitrary attribute you identify is sloppy argumentation; somehow I don't think you would argue that someone supporting police having the authority to use force means they are supporting every instance including illegal uses of force.
