The value of life

20 years ago, my fathers sister was killed by her husband. Stabed 7 times while holding and protecting her daughter ( my cousin) When my father came home, he saw his sister down on the floor in a pudle of blood, reaching for her daughter, while her husband was handcuffed and crying for what he did... This was my fathers worst moment in his life. After 3 years in prison the husband got out, because of over crowding and good behavior. Which is pathetic, I mean the value of life means nothing to humans. I person cant take another persons life and get away with just a few years in prison. Am not saying that all the killers in the world get 3-5 years in prison, but not even an eternity in prison wont pay bach the price of life. So why doesent the law have this rule that for life you have to pay with a life. I mean I know that, people can change, but its not fare... A killer is a killer, his hands are forever staned with the blood of his victim... This isnt justice.... This is just giving chances, to those who rearly deserve them. I mean with this kind of order the level of killings would go down, I think...
