In certain cases, capital punishment should be used on criminals. If there is a legitimate danger to society who is accused of certain crimes such as killing and raping children, mass mudrder, or a few other severe crimes, then capital punishment should be used. We shouldn't have to pay taxes to keep them alive.
How can our govt. Kill criminals for killing people. Its hypocritical. The govt. Gets to judge and choose who to kill and who to lock up who are they to judge I mean lets get real if you haven't walk in that persons shoes don't judge them. Locking up a criminal and rehabilitating him or her works better then just killing them.
The American justice system is broken. Instead of capital punishment, try rehabbing criminals. If rehab doesn't work, have the most dangerous criminals do hard labor to carry out their sentence. Killing someone isn't necessary--instead of death, someone should repay their debt to society by working it off for their entire life.
It cost more than housing a criminal for their entire life to have them put to death. Other than the need for the victims or relations of victims to get revenge and satisfaction it doesn't provide anything that a life sentence doesn't. People also have more time to think about their actions which may be more punishment than a quick death when they spend the rest of their existence in a cage.
