This isn't a matter of criminal liability, it's one of immediate survival. If a violent aggressor who is shot happens to survive, the court can decide their fate later, but that's completely separate from the right to self defense. This is the law that we, a civilized society, live by. If you don't like it, there are countries (UK!) where self-defense is almost entirely illegal - they may be more fitting. Furthermore, we decree the right to self-defense as a _natural_ right, not one that could be potentially amended away.
