From what I understand from reading Bleach all these years, there is the elephant in the room that everyone seemingly avoids talking about.
Hollows, and why aren't all of them killed on sight?
A hollow is a human soul,
Gillians are consisted of hundreds of hollows that mass together into a single existence meaning those unfortunate souls still exist in the hollow and thus not purified when eating each other.
Adjuchas are Gillians who have consumed enough of other Gillians and evolved. (Soul count in the hundred thousand range here.
Finally Vasto Lorde are Adjuchas who consumed enough Adjuchas to evolve (Soul count in the tens of millions if not hundred of millions contained within a single Vasto Lorde)

So question is, why 'humanize' hollows, and Arrancars. It would be the right thing to do to kill them all and purify those souls so they can go to SS and reincarnate again instead of being stuck in eternal torment within a hollow for hundreds if not thousands of years before a Shinigami comes along to kill the hollow. We're seeing multiple Billion souls that haven't been returned to the cycle of reincarnation because main cast is too busy makes friends with the monsters. People's mothers, fathers, friends, children are stuck inside those abominations
