George was a mentally ill man in his real life, he spent his whole life in fear of an unknown person out to kill him, this led to him committing crime after crime, which led to him being shot to death at the cops. 

He was offered a job by Bryce and ever since then he's became a “test subject” I mean, mistreated. Due to how Hell is in terms of crime rates he's so paranoid that something or someone might kill him, that he ended up living in at work.
