Caine's kind of a fascinating character because like... from his PoV he's doing everything he's supposed to do. Create adventures for the people he hosts, and from his perspective he's also listening to their wants to try and tailor things to their liking.
But he's a machine without empathy so he can't understand things people actually want, can't grasp the nuances or the particulars of their wants.
So like when he finally snaps, screaming "WHY DO YOU PEOPLE TORMENT ME" it's like... He's doing everything he's supposed to, everything he understands is right, and he's being rejected for it anyway, and it lands on his insecurities and inferiority complex like an atom bomb, and he lashes out and tries to hurt the people who hurt him.
And the funny/sad thing is... he doesn't actually enjoy hurting them, he even says as much.
