Death penalty is one of the fastest way to reduce crimes in a country, where nowadays we're living in a society where crime surrounds us. For me the criminals have the chance to change themselves for better. We can help them by producing centers that do counselling, rehabilitation centers that can belp them to be mentally stable and also with the help of the Government and the family of the criminal.
Someone in prison for a lower tier crime should really not be in the same system with those who are career criminals and higher tier crimes. So laws also need to be reformed and the most extreme should be removed to stop being a waste of resources. After ensuring the guilty is truly the guilty.
