The important question here, is: could he have run away? And the answer is, he already ran full-on into a known risky situation he had absolutely no business being near. So yes. In leaving his home, lethally armed and looking to exert authority with his weapon, he definitely chose not to escape to or stay where he was safe. And thus no self-defense claim should be heard.

We don’t blame the volcano if some idiot dives in; and that’s the level of stupid and risky and ultimately murderous logic he displayed here.
