Short story a little longer he marched a private army towards Moscow, was a little too successful, took a vacation to Belarus, returned to Moscow for some insane reason, plane exploded when he was leaving.
It's the same kind of suicide which your death was ruled in the Wild West when you "opened fire from a distance with a pistol on someone with a rifle".
He tried to intimidate the ruzzki minister of defense and made pootin angry with that.
Lesson was/still is: Don't make psychopathic killers angry, they know only one outlet for their feelings.
Lesson is, when you commit to marching on Moscow, DON'T FLIPPING STOP!
He's probably still alive and being tortured somewhere.
He's definitely got OP magic abilities. And a huge harem. Its a romcom under the pretenses of a fantasy adventure, 100%.
He would get merc'd by a slime that took advantage of his hubris on day 1.
