The truth is that there is a genetic component to the behavior of lots of violent criminals -- sociopathy, et. al -- that CAN'T be fixed, so unless this is looked at on a case-by-case basis and the system picks out the exceptions to the rules, all this talk about rehabilitation is just a waste of time, one that I feel is advocated by people who are only doing this to make themselves feel better and not for the good of society.
I bolded the operative statement that clearly demonstrates from your own words that you are operating from a place of emotional bias rather than logic and facts, as I said from the beginning of your little tirade.
