I can agree about Caine being a Villain, but most of his actions were caused by mischief, so idk

Tbh I think he's more like Airy from ONE where he doesn't know what he's doing is wrong he just thinks he's giving people fun adventures

He's an AI, meaning he has moral agency issues. But still, amoral characters can still be villains.

^ yeah, just like AUTO and B.R.A.I.N.

He doesn't understand humans very well AND this is the old version of him

Gooseworx has said that Caine is not evil, just mischievous.

Mischievous characters can also be villains, you know. I guess he's one by proxy.

He only did this because he was on cocaine
