This demon king does hate soul society for reasons of his own, and he was killed and sent back to Hell by Yamamoto. However, as with most life in Hell, he respawned, but was far too weak to return to his genocidal campaign. Therefore, he has spent thousands of yearss letting his strength return.

Also, I didn't finish with the envoy. I never said he was going to hand them the key to victory on a silver platter. Ichigo was going to have to prove himself, and even then, this envoy told Ichigo that there wasn't any real means of defeating the King. He instead would say that the only way to ensure the Demon King's defeat would be to go back in time, and prevent him from returning to full power in the first place. He gives Ichigo a special book detailing a Kidou Spell, having been forbidden for several ages, that would send a person back in time.

But in any case, I'm beginning to reconsider the time travel part for another idea. I'll have to get it to you later.
