+ he cut Hiyori in half when she attacked Aizen in rage over his words in FKT, and seemingly almost killed her, even though it was toned down in the anime to merely impaling her.

I think that although his goal was for the sake of goodness, by killing Aizen, he committed so many crimes along the road that he probably would have got some kind of punishment after all.

I wonder when he found out how to avoid Aizen's Shikai, though. If he knew the trick for a long time, he should, if just for his own sake, have taken action earlier. He was likely waiting for the right opportunity, but I wonder if he could have done it earlier than he did.
