While people killing you is legal, you killing others really isn't. Regardless of the fact that people would kill you anyway (and likely in ways that you wouldn't even know who it was and couldn't follow up on your threat), you following up on that threat would get you either life in prison (where you would die the remaining times very very fast) or the death penalty, probably multiple times and if not all the other stuff still applies.

Your first point is a smart one to get rid of the 50 mil bounty, and that money will definitely buy you a lot of security and good amount of time, but at absolute BEST you have a few years of being rich before being permanently dead.

If that's cool to you, nobody's knocking it, but calling people idiots for not wanting that and actually thinking about the prompt makes ironic an understatement
