I was looking for one specific quote from Sousuke Aizen but I was not able to find it, I googled it and watch some of the scenes that I believe he says it but didn't really find it.

If I recall correctly I believe he says it to Ukitake and I think it goes something like this:

"...You are blinded by your self-rightfulness..."

Or something like that but I wanted to remember it correctly and the context of which it happened. If someone remembers it properly it would greatly appreciated!
