theres another character in the show named entrapta, who is your stereotypical "i'm quirky i'm mentally ill that means i don't care about other people and no one really understands me" type of character.

she was on the side of the good guys but was captured by the horde and manipulated into joining them instead (with a focus on the idea of "she's mentally ill she doesn't understand right from wrong so she'll help us commit war crimes and genocide" and then she did)

last season with entrapta being captured by hordak there was a lot of buildup to the idea of hordak being redeemed/hordak and entrapta getting together, but nothing ever happened with it.
