I think he would, those two seem to have plans that they go with despite the damage it'll do, heck Shiva implied Trihexa's attack is gonna give him more reason to war against Shiva. Indra and Hades... I swear they may be strong gods, but they're incredibly stupid too.

Though I don't think Hades will be in the tournament for one possible reason, the rumor is Malebranch will be the antagonists of this story arc. I bet during Trihexa's rampage, the Grim Reapers and Hades' realms took a major hit, and in the process... the members of Malebranch escaped their prison.
