If you want it to be that cut and dry, then anyone that would of taken his life would then no longer have basic human rights. If you want to paint with a wide brush, then that’s fine. I’d rather say that everyone deserves basic human rights, whether you are the most disgusting human being on the planet or the pope.
But if anyone that takes a human life no longer possesses basic human rights, then thats fine. But you can’t just pick and choose.
