God set before us life and death, blessing and cursing and establish reward and punishment which is eternal life and eternal damnation.
Death Penalty is not a deterrent to commit evil deed or heinous crime because even the Eternal Death Penalty set by God are ignored.
Therefore, death penalty is not a deterrent but a punishment for those people who opted to violate rules and the calling commanded on them to follow and obey.
The question now to the would be offenders is this; Why should you die before the time of your death set by God?
Eccles 7:17 Be not over much wicked, neither be thou foolish: why shouldst thou die before thy time?
All of us shall be judged according to our works while we lived whether death is caused by man or by the stipulated death set by God.
The compelling reason for a President to impose death penalty to a country damaged by corruption in government, illegal drugs and rampant criminality is therefore biblical. The imposition should not be prevented by human right advocates protecting the human rights of criminals more than the victims and by the religious groups pretending to be biblical but never ever come to the knowledge of the truth.
