Asrafrate: I don't think he'll ever be set free.
Look at what happened with Ian Brady and Myra Hindley (Moors murders.) Those two did appeal after appeal, claimed they'd been in jail for enough time. Claimed remorse and all sorts but the Brits never released them. Hindley is dead now, and I don't think Brady will ever see beyond the prison bars.
What this guy did, yeah, the chances of him being freed? Nah.
What was the cost of that? What was the impact of allowing that (Parole Hearings and appeals) to the families of the people they killed? Is that fair?
