Do Y'all Remember That Time Harukawa Said That The Darker The Eyes Of The Character The More 'corrupted'

Do y'all remember that time Harukawa said that the darker the eyes of the character the more 'corrupted' they are? The whole Tanizaki debate where people were saying that his eyes often get darker, meaning he'll be the one to join the mafia? Well, has anyone ever considered Fyodor in this case? Usually, his eyes are either a bit shaded or completely white

For in stance in the panel above, his eyes are grey-ish. Never pure black like PM Dazai or Akutagawa. This is what they are usually like.

And in this panel, his eyes are pure white, even though he is (supposedly) lying about the split-personality thing.

I'm pretty sure this is the only panel where his eyes are straight up black.

Just pitch black. Even when he turns into Bram they aren't this dark. What does this mean in terms of his character. Are his eyes usually white because he considers his cause just? Or is he hiding something else?
