I agree in the case with certain prisoners that rehabilitation is better than being punished for life but that is a very specific issue. Same with Tom's issue about abuse, which sound like a really logical point to me. Also, it does not count for all prisoners. It's also not only about love in these cases but also about pragmatism.
When it involves predators of children, you have to ask yourself... is the 'chance' they may be 'rehabilitated' worth risking another child's life. The answer should always, and very loudly be... NO They should either be killed or locked away in a very very tiny cell for the rest of their lives... as in until they are dead. If someone wants to argue this, I suggest they go explain it to children who have been preyed upon by someone who was 'rehabilitated' and released.
Hate is not the inverse of love. Indifference is the inverse of love. Whereas hate is the inverse of fear. And all forms of fear are incapable of existing where there is love. We as a society are so assaulted by negative garbarge and its justifications that not only does the idea of "just loving" appear to be an over-simplifcation. It also appears to be laughable when viewed from within our current paradigm. Fortunately and unfortunately, our problems just aren't that big and the solution is both that simple and that difficult to accept and even harder to do. But when you divorce yourself from the state, culture, etc. You see that love is the only solution. As a college of mine once told me, If you only seen the amount of research and people willing to do something to reform our current system of "punishment," you would just break down and cry. So much time and effort has been devoted by so many people into studying this current system. That to say that we don't have the solutions to rehabilitate everyone is just ridiculous. There isn't a prison warden in this nation that doesn't want to try and impliment some of these ideas. But time and time again, the solution that costs the least and maximizes profits is chosen. There is a vulgar but very true idiom amongst lawyers that deal mainly in criminal law. "If you give a man 30 days or less, you will be lucky to ever see him again. But get a man 90 days to 6 months, he will eventually get a year to 18 months. And if you can get him a year, you will eventually get 3 years or more. And once he gets 3 years, it's game over. The sky is the limit."
One thing Love is not, is conditional. Human ignorance makes "love" conditional. True suffering there.
