I believe that we just borrow our lives from God. And He is the only one who have right to take them away from us.
God is the only one who will decide to end the life of a person. So I am against death penalty. Sinners need a second chance in their life. I am only in favor of imprisonment.
When you read the bible there are instances where people commit very heinous crimes and GOD's judgement was for them to be executed , if you take a cue from that we can effectively use the death penalty on so many crimes especially in any action that leads to a person's death then the death penalty should be upheld there.
