Theory time!

Maybe those "Dragon Gods" are the same as Elefseria, or he might even be one of them. And the truth isn't that the Dragons need sealing, but that the other Dragons (or actually self-taught Dragon Slayers like him) want to stay uninvolved and make sure he stays that same way, but he wants to rule the world.

Alone he can't hope to defeat his former comrades, so he hires others to do his dirty work for him, intending to then ambush and defeat his helpers while they are still weak from dealing with the "evil Dragons".

Or maybe it's just lazy writing. ^^
