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.
For me I am not ok with death penalty,
I preferred let the person have a chance to repent and dont do what he did..They might punish him like clean the toilet everyday, go farming and of course to read the bible.
I am not in favor of death penalty as well. The suspect should be given a chance to have a new understanding about life. How precious our life would be. But if if he doesn't change at all and commit crimes again despite of the chancr that was granted to him. Then death penalty must be the punishment.
