The CoDD trio would be such a pain in the ass to deal with for the RLE crew and Anguish. They're just very violent and unfortunately cant control it. At this point all they are are just Killcodes. Not a bit of coding of who they were before hasnt been corrupted by the Killcode. They'll have to be kept away from Suns and Moons, as well as be able to have access to blood. If that's what those guys want to deal with then they can go right ahead lol, they should just know what they're getting themselves into
rle crew would definitely have issues with Lust, Glitter, and Pride being present.
Anguish on the other hand is from a offshoot where Moon killed Eclipse so Anguish lives alone now. He only has the star and a few mementos from Eclipse. He is mostly sad and scared right now, but it will almost definitely turn to bitterness. The big question is if he will end up more angry or sorrowful. So it's possible he might be down with the trio murdering his old family, specifically Moon.
Really anyone is better than no one, so if his best option might be the damned, maybe he will take it.
