If you kill someone, you practically took away his chance to life a full life. Given you cannot bring him back to life, there is really no other way to be responsible unless your chance is take away too. The difference between life and non life sentence is not a fundamental difference but simply scale, in my opinion.
Another thing is...punishment by law is just one form of punishment, in many way it is the more civil punishment too, even if law doesn't get to you, will your social circle accept you? If crime goes unpunished, you probably won't find a place in the society besides among other criminals, and psychologically you won't get over it.

After that he still will be in prison, and the case will be evaluated each 5 years after that (at 36 years, 41 years, 46 years and so on), and from this evaluation the person can be released or kept in prison. I think it's safe to say that this guy is never going to get released.
