You can love a character & still admit when they’re wrong. i love unohana but i acknowledge her flaws (none she’s perfect) & can hold her accountable for her wrongdoings (she’s never done anything wrong in her life) & call her out on her actions (which are always right)
Thinking maybe unohana's hell appearance could be this or similar esp since this version of her is due to having achieved power stronger than bankai and in the hell arc her name being the death sword
