Imprisoned for years without trial is not a slap on the wrist. For a normal person this would usually be life-destroying. Any normal person would take about a minute to think things over and then immediately hang himself if faced with being Chris.
Chris is Teflon only because he's too stupid to realize how bad his situation is, has no ambition for anything more, is delusional enough to cope and has absolutely no shame. He doesn't even care enough about other people to be hurt by rejection.
Physical pain, exposure to the elements and hunger are the only punishments that would get through to him, so he's going to stay Teflon until he starts living on the streets.
