Capital punishment is easily proven effective because the criminals aren't around to commit other crimes and kill other innocent people. If individuals can't function properly in society, they should be taken out of it. Life is a privilege and should be respected. Those who end innocent lives should have theirs ended in return. Murderers should not get lifetime room and board with three meals daily, cable TV, health care, exercise, and education.
Murderers receive more benefits than some lower class families.
All at the taxpayers' expense. Some would argue that this method of justice is immoral, yet those that deserve capital punishment are immoral. Society should have the right to kill in defense of its members, just as an individual has the right to kill in self-defense. People worry that the murderer will experience pain when he receives capital punishment, yet his victims experience just as much pain if not more. Morals are different for every person, yet all decent people believe murdering innocent people is wrong.
