AHEM WELL, I don’t think anyone liked seeing the moiral pair culled and the events that followed after that, But I really think that there’s a lot more to surface then just “ahaha funny emotionless murder clown kill everyone”
It’s really important to go back and see what Gamzee was even doing before anything happened. He wanted to quit his sofer addiction for his friends, for his best friends who have stood by him for as long as he knows. Especially Karkat’s encouragement!
But because of this very quick cold turkey of his addiction he most likely became very vulnerable.
Which is why he was able to be mind-controlled so easily by the Cal doll/Cailborn’s mind control through that doll

And it was nice to see how much Karkat truly cared for his best friend and wanted him to get better <>
HOWEVER, yes there are a lot of things I would have liked to see more of or changed. It really would have been great to see Gamzee before the cal doll was even there and he was by himself in his halfway sober state by himself. Gamzee has a lot of mystery to him as a character even before this arc so it would have been nice to really see what he was thinking about.
I could go on and on and on but this is already too long aha! Thanks for letting me ramble
