No, but there are very specific circumstances that can occur to result in a murder

If it can be psychologically proven that an individual is a sociopath or a psychopath, I believe the death sentence is perfectly justifiable in that scenario. If an individual had reason such as the victim had assaulted, permanently damaged or murdered family or someone close to the perpetrator then I'd find parole justifiable beneath fifteen years. If someone is murdered due to insanity then the perpetrator goes to jail just like that. If there are other circumstances then in most scenarios a life sentence is probably justifiable.
