It's a nay for death penalty. Though the person has committed crimes under the law. We shouldn't be the one to decide on their deaths. The best way would be to let them live their lives inside prison day by day and regret everything they've done. Sure regret doesn't come easy to cold-blooded people who are used to doing it but sentencing them for a long time gives them a chance to think and just maybe change. It's never too late to change.
