Yes, death penalty should be abolished.
My reasons are
It could be used as a tool of revenge in a biased judiciary system.Most underdeveloped countries have their judiciary at the Apex of corruption. I'm a witness to this.
Religiously, Both the Bible and the Quran does not support death sentence by sentiment intact the Bible outrightly said thou shall not kill.
3.Death sentence has caused much death in prisons today where Victims kill inmates with the reason that "I" "will" "not" "die" "alone".By killing people you are simply burying dreams and this does not support societal growth.
Furthermore, death shouldn't be forced on an individual no Matter the offense rather live imprisonment should be applied to avoid the death of youths in the society because most horror offenses are committed by the youths
