To someone like CW, who comes across to me as being a nebbish, a person who is basically just there, not a go getter, and eventually a proven coward, I think prison in some kind of confinement from getting killed will be fine for him. Maybe that sounds too snarky, but for the rest of his life, probably 40+ years to go, he doesn't have to think for one minute how to put food on the table, a roof over his head, provide for other people, smile when he isn't really participating, etc. Free medical. I don't know who pays for the books, but probably he gets access to a library or things sent to him by family and sycophants wanting to marry him.
So I just don't see it as such a bad place for a guy who first of all did something horrible, but secondly will probably do better in prison, if not murdered, than he did on the outside.
That's just how I look at it, assuming he gets books, (tv? internet? mail?) I really doubt he'll kill himself. Just that he needs to look out for others who might want to kill him, and if he is in some kind of protective custody, he will have a decent life. I think he has probably already switched it all around in his mind that one way or another it was all her fault.
ETA do convicted murderers in Colorado ever get conjugal visits? If so, he'll just marry someone with money, to bring him things and get his rocks off once in awhile. I see that in Peru, JVDS got married, either had a kid or is about to, and down there they have regular conjugal visits, even though being a convicted murderer. (Of a Peruvian lady, not Natalee).
