Even if he somehow finds a way to maintain the balance of his existence after acquiring the pathway of undying, the divine flesh of the pathway of undying will only add to his stress and make it more difficult to maintain the balance and make it easier for him to lose control.
So he can do what the killer in the energy spring is doing and have two pathways. The best he can do is admire their foolish decision while eating popcorn.
For now, he doesn't plan to intervene in the fight. There is just nothing to gain yet by doing that.
He doesn't want to show himself easily, or the nobles of the city will become wary and target him. He also doesn't want to expose his location to the other avatars, as they might try to kill him to gain control of the main body.
So he watched with rapt attention. As he watched, things became heated because the head of the killer in the energy spring had become exposed.
