I think his handlers know trying to get Lucas to change is a wasted effort. They probably know it is a big waste of resources to put Lucas in the nuthouse. He will just come out and return to his Lolcow ways. They just have to do some damage control and give him his tardbucks and flophouse room and make sure he doesn't go to far off the rails and become violent.
For at least a year, people in KF and SOFALAW have been looking at his escalating antics when he's manic and our reaction is, "Look, it's any time now before he goes back to the nuthouse," and every time he manages to survive. At this point, I'm convinced the only thing that'll get him locked back up where he belongs is if he commits some kind of act of violence.
