While I accept that he may have totally changed he just doesn't deserve to be walking free after what he did.
This is it exactly. We're not talking about a bank robber or a drug dealer that could be rehabilitated and may not have killed anyone. We're talking about a psychopath who raped and murdered a young girl. He then had three years to reflect that was an horrendous thing to do and regret it. Did he do that? No the fucker obviously enjoyed it, thought it was easy as he'd got away with it, so he did it again. I don't care if he's grown a pair of fucking angel wings in prison, nothing is giving those girls their lives back or easing their relatives pain. He should be in prison until he dies. It's a fitting punishment for his crimes, well it is as he couldn't drop through a trapdoor with a rope around his neck.
