Why is the Death Penalty Good?

The death penalty really isn’t good. Crime statistics for Texas actually went up after they introduced the death penalty, so fighting crime obviously isn’t the reason. Quick and painless isn’t the reason either, because most research points to the fact that lethal injection often fails to knock the person out before they die of the massive heart attack, and so they are paralyzed while suffering great pain. So the question comes down to is it OK to take another person’s life? In my opinion, even if it costs me an extra three dollars a month in taxes, I’d rather pay for them to stay in jail until they die naturally, rather than pay someone else to kill them.
