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.
What about those people who kill and got killed because of religion or their beliefs? And the war also.
But I believe that death penalty is not necessary, you could just imprisoned those criminals for the rest of their lives, unless they got escaped 😂.
To kill someone as a punishment is very barbaric and has nothing to do with a modern society
But we used 💉 injected poison (whatever you called it) unlike before who cut the head haha (peace 😂)
