Even if Zanpakutou killed him, if we follow Hell Verse's logic (uncanon as it may be), Ulquiorra would more than likely go to Hell. He was undeniably evil, and as an Arrancar, he had a tangible will and personality. But as Kami said, we don't really know what happens to an Arrancar when it is killed.
