Fifteen cents is roughly the cost of a small informational pamphlet (likely more if printed with color and laminated but I have taken some artistic liberty in my previous comment), and prison is just one solution to a wider class of social impairments of which sociopathy is just one instance. Other instances of solutions share the quality of being unpleasant but necessary things any civilized society devotes energy to by learned necessity and include a functioning constitution, military, legislature, courts, police, and more. I thought this was clear but on rereading I see maybe I have failed; thanks for asking.
