I have my own very definite ideas about this. If someone goes out to deliberately rape or murder, they don't deserve anything in the way of human rights, and serial murderers can't, in my humble opinion, be "rehabilitated". They're sick individuals, and if the death penalty can't or won't be implemented, then these people should be locked up forever. Better still - I agree with ladybird. Send these hideous people off to Siberia or somewhere, and make them work in chain gangs.
