Here's the thing about that: the purpose of justice is not to punish criminals or make them "pay" for their crimes. How could a murderer ever repay his victims or their families? What's done is done. No, the actual purpose is to try to prevent more such crimes in the future. Sometimes that means making an example of criminals to deter other potential criminals. Sometimes that means locking up the criminal so he can't re-offend while contained. Sometimes that even means rehabilitation so the criminal won't re-offend even when released.
Most of that can't actually apply to Chris, though. You don't need to make an example of him, because who the fuck would want to be him or do what he's done? He will NEVER be rehabilitated. The best you can do is contain him, and if you can do that at his own expense, why wouldn't you>
Also sending Chris to a tard depository might seem like the soft option compared to prison, but Chris will likely hate it far, far more.
