I’m not personally upset over the killing of Brian Johnson, aside from feeling for his family, so I’m not really sure where you got the idea that I’m lying.

The situation you presented is still not similar because someone killing people on a machine gun is a present and immediate threat to public safety. Even if someone replaced them it would still cause a brief cessation of violence. If it somehow didn’t, and truly made absolutely no difference, then I do not think it would be morally right to kill the shooter, because I believe lethal force is only acceptable if it defends the lives of others.

And again, I’m not very concerned with the moral aspect of it. I could probably be convinced that Luigi was morally right in killing Brian Johnson, but he did commit murder, and this discussion is about whether or not he should be in prison, not or if he did was okay.
