If free will was not real

I think it's correct to recondition them/their brain in order to turn them into a good person that contributes to society in a positive way. And that's not what's happening at the moment.

I agree completely but only if it can be done.

I'm against the death penalthy. I'm not sure where I stand when it comes to lifetime imprisonment for murderers but I guess permanent detainment for people capable of murdering someone is a good idea if and only if attempting to rehabilitate is too risky.

I would expect rehabilitation for murderers to have a very very very high success rate if we are to allow them back into the community and consider them now to be fully reformed non-murderers.

I'd say it's wrong to imprison someone, lifetime, for doing something they're ultimately not responsible for. The correct thing to do would be imprisoning them until they've been rehabilitated, if possible, that is.

Me too. However, from the victim's loved ones point of view, I'd probably hate, and want to (not necessarily would) just beat the shit out of the murderer, even though I wouldn't think it's the correct thing to do. So I don't know how that would work out among other people in society. 

If rehabilitation isn't possible then I'd agree with a lifetime prison, because of the risk of the murderer, harming other people again, unless something better comes up. But I think in the future when genetic modification becomes a common thing and when people start becoming more science-y, education increases and becomes worldwide, in turn making society good, then I don't think we'll even have to worry about murderers, rapists etc.
