I think you've somehow gotten the victims in this world reversed. Have you ever had something stolen from you? Someone close to you raped beaten or even killed? Maybe a bit of experience in the real world would knock some sense into you. Your bleeding heart for criminals (of all people) is making the world worse for the rest of us. Not that it should have to be said but to be clear... the victims of crimes are the victims... not the criminals.
I've been beaten and had things stolen from me. Still I do not share your view.
"making the world worse for the rest of us" - I believe that the "rest of you" are making the world worse for the rest of us by turning people who could be normal into hardened incorrigibles looking out for a revenge.
I am not for not prosecuting criminals. I am for not overdoing it and and for giving a fair chance for people who had made a mistake but are perfectly capable of leading normal lives. I am not advocating letting serial killer walk free and incognito.
