Odin was essentially a deceiver, claiming he would gather the Ultimate Force Alliance's strongest forces to help Forseti seize the power of the sacred halo, only to bring him to a place where the power of the sacred halo might exist.
Whether Forseti could actually obtain it was left to his own abilities.
As for the strand of divine flame Forseti won, Odin kept his promise and gave it to him.
"The rest is up to you." Odin now seemed uninterested in the power of the sacred halo because the major powers, including himself, had agreed that high-ranking gods should no longer vie for it.
This agreement also included Hades, who had already benefited greatly from obtaining two top-tier divine artifacts. Naturally, there was no need for him to contest for anything else!
Obtaining the power of the sacred halo, in reality, is more about gaining the recognition of a Cosmic Entity, which also subjects one to various restrictions by the Cosmic Entity.
