No shit it doesn't absolve his former crime. Sounds like he was convicted and met the requirements for release. That's how the justice system is supposed to work. You know, justly.
The idea that someone doesn't deserve sympathy for
serving 16 years for an act they didn't commit because they were previously convicted of a similar crime is idiocy. It completely overlooks why sentencing follows certain guidelines and the entire concept of rehabilitation and release. Do you think people who commit crimes are subhuman? Guess what, people can err, yes, even rape, serve time, and reenter society. Whether a person can be rehabilitated depends on a number of factors. I have personally met rehabilitated murderers with genuine remorse, and after hearing their stories in depth I have an incredible amount of sympathy for them. You know it's possible to have compassion for both criminals and victims as living breathing human beings without condoning the crime committed,
right?
I don't know how old you are, or what path you're on in this life up until now, but maybe you should pause and reflect a little before you judge someone else's undue suffering from a few blurbs. You might find yourself in circumstances at some point that humble you, and I doubt you'd find comfort if someone else took such a cavalier attitude towards your life even if you had made some sort of transgression along the way and paid your debt to society.
