Well... he was a lot younger than Makarov for one thing. For another the Alvarez army is more than a million, if memory serves, while Magnolia held "only" around 70.000 citizens plus however many tourists, so at most 100.000.

So I imagine he'd have survived, but turned into an old man... until the whole country, every mage guild, the council and all ten wizard saints came after him. If there's anything that would warrant the death penalty, it'd be the intentional killing of several tens of thousands of innocent bystanders... if they even tried to take him alive and put him before a judge to begin with, isntead of just making a man-hunt out of it.
