Trtr has a big snuff fetish that bleeds into all of his writing. It's why the Monsters as a whole are fucking terrible and Ilias is completely justified in killing them despite what Trtr tries to tell us.

The Ancestors suffered due to his snuff fetish, Trtr realised too late in part 3 development that the Monster side far worse than the Angel side, so Kanade had her personality and role in the story deleted completely and Monster World Tamamo's Dr Mengele tendancies got dialed down a lot.

But part 3's writing suffered from a lot of rewrites anyway, we know that both Monster and Angel routes were cut down dramatically based off clues left in the files and the creation date of certain characters. For example Baal Zebub the Hivemind Calamity in the Chaos route was created years before almost every other Chaos route boss and it's much more likely she was just the original Beelzebub queen that Alice 1 had to seal away.

Luka was likely going to be seperated from the party during both routes and turned into the Worldbreaker and Judgement in each route and Trtr walked back on this decision too late after thinking about the party not having access to Luka for so long, evidence being unused faces for both and the forms just randomly appearing at the end of the route.
Nuruko likely had a much bigger role and either was Chaos or something close to it based off pic-related clearly meant to be Hilde's child and adult Nuruko has the exact same mask. But this one is a bit harder to argue because Chaos was drawn back in 2014.
