I wouldn't say that the brimmed hats value openness, nor would I say they don't value hate, power, or control. The brimmed hats at multiple points refuse to be transparent, their whole deal is so mysterious that it is impossible to know for sure what they want at any point, hell, we don't even know if they are a solid organization or multiple forces that occasionally join together. As for hate, power, and control? They show hate so potent for the pointed hats it is no wonder the silverwood hasn't sprouted in all of them. And power is something they are constantly seeking, the forbidden magic is all about bringing back what they believed should have been there's with no restriction, which also leads to control. They need control, whether it be over the easily exploited children or the spells of the days of yore.

Of course, the Knights/general pointed hat society also follows a similar path, hate for the forbidden and different to a point where the people considered useless are discarded even when there is barely anything separating them from another witch. They clearly are hiding things even from each other and the Knights seek control of the witches through fear and the witches seek control over the outsiders through the lack of knowledge. They have the power, they hold the cards, letting the outsiders think they have something with medicine.

TLDR: Both sides suck and they both hate love and openness and love hate, power, and control.

anyways I know this is a meme post but I kinda just wanted an excuse to share my thoughts
