That makes since sure. But just because a soul is in hell doesn't mean it's destroyed like the quincy kills. There's also the chance that something happening IN hell fixes the soul or something before it's returned. I certainly don't know. It's all speculation no doubt. I just thought I was interesting that he did an entire manga chapter on Shirker, and then NEVER brought it back again. I'm excluding the Imaginary Number 1 cause I think kubo was kinda forced into that one.
