Explanation:

I used to be against it as an individual, when once you were sentenced, you did your time. If you were sentenced to life, prison was where you died. I tend to lean towards the death penalty, depending on the crime, of course. In my opinion, our judicial system, always has room for improvements. Hope this helps.
