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.
Personally, I think that death penalty is too brutal for me as a punishment for criminals. However, there comes a time when a crime committed is too bloody and inhumane that I feel that only death penalty is the rightful punishment.
We must implement the death penalty in order to maintain the peace and order or the world. We must trust our government that they will give equal justice to everyone. We don't have to be afraid even there is death penalty if we act ethical and legal. Only who violate the law will be affected by that law so its not alarming for me.
