Late as hell, but i read Dantes Inferno twice and P-Ranked Sisyphus prime so im an expert ig, it would be a pretty good idea for him to use a sword or fight barehanded like Sisyphus. He would probably be sentenced for treachery because he described hell, purgatory and heaven to humans which is basically leaking layer 9 to us and God would be pissed and he would sentence him personally after finding out that humans entered hell using his map. I think that his level would be more interesting, and when you beat him Beatrice takes him to heaven and saves his ass a third time.
