Better be careful sugar --- mods are watching for people dropping insults like that. And it always kind of brings shame upon the person when you have to results to such responses.
Intent doesn't matter. It just plain doesn't. If I'm at the range, think my gun is clear and have an accidental discharge that kills someone, does my intent matter? No. This board is full of people that claim that there is no excuse for intent on infringement of the 2A and the same is true on speech. It's censored or it's not. Whether there is intent driving the censorship is not the question. That's a separate exercise in asking "are we okay with this censorship".
Intent does matter in your scenario. There is the difference between murder and manslaughter. As far as the Second Amendment goes, there is no leeway in the context of "shall not be infringed."
If I accidentally kill someone, the worse I could be convicted of is manslaughter if at all. I should not be prohibited from keeping and bearing arms. If I murder someone, I still do not lose the right and should not be prohibited from exercising the right. If I am such a risk to society, if I'm not executed, I should never be released upon society until it can be proven in a court of law that I am no longer a danger.
