Criminal Justice

I tend to categorize crimes into at least three different categories. 

Victimless crimes: All of which are behavioral issues best treated as "illness."  Society may have valid reasons for prevention, but treatment in secured facilities if necessary is the only humane solution.  

Crimes against other people: Possibly behavioral issues, but society cannot afford not to have severe deterrence penalties.  Up to permanently removing the behavioral issues from the gene pool if possible, and from society if not.  

Crimes against society: Up to and including treason.  Deterrence penalties appropriate to the crime are the only possible solution.  Legislators may argue about "appropriate" but deterrence is the only solution.  Note that the deterrence is a cost benefit issue for the criminal.  Most famously "I only regret that I have but one life to give for my country,"
