No.
The reason I oppose life imprisonment isn't because I believe everybody should always get out of jail at some point. I simply believe the possibility should exist. No matter how heinous the crime, I have to believe that everyone has within themselves the possibility to redeem themselves.
Of course, the more heinous the crime, the harder the burden of what constitutes redemption should be, and in a case like this it might be effectively insurmountable, but still.
Psychopaths are incapable of reforming themselves into better people. Any adaptation to their character will be for the purpose of better hiding what they truly are. You cannot teach a psychopath empathy or remorse, their brains aren't wired to view people as anything other than objects. At most, you can only socially reengineer them, but you cannot cure them.
