That's the point.
A community does not have to kill a convict.
Life imprisonment shows the true nature of that community, imo.
It's also becoming increasingly hard to keep so many convicts imprisoned for life. We already have overcrowding problems as is. Serial Rapist (of any kind child or adult) that have done it more than once, and murderers who have multiple kills (that's not out of emotion) should be put down imo.
I guess that a lot of convicts committed their murders and manslaughters having lost control of their emotions.
I can forgive a murderer. I have no sympathy for anyone that would harm a child.
