Cass is remorseful, flawed and very hurt, he doesn't try to be rude he's usually quiet but very nice to those who speaks to him and he doesn't mind engaging in philosophical topics, he blames himself for a lot of things and can't handle disappointing people, he's a small bit delusional but he never will hurt a soul and he'll never go crazy if he disappoints you he just sulks in his pain because he knows people don't suffer the same fate as him and that in itself is enough.
