The grey area of the debate-What is it?

There is a grey area in this debate, to be frank. The majority of “factual evidence” people provide to back up their information online is merely opinionated ideas. People are mainly discussing the morality of the death penalty, calling it barbaric or justice for the victims and their families. Race and demographics are discussed a lot in this day and age as mentioned before. There are questions that need to be answered. Such as why is the death penalty more effective than life in prison without parole? Why are statistics showing that more African Americans have been charged and put to death throughout history? Do the pros outweigh the cons when having to decide whether or not a person gets to live?
