Overall, 55 percent of Americans support capital punishment, and 37 percent are opposed.<quoted text>I can't agree with Kant, or with you. A civilized society has no such right. Rational behavior is not immoral.
Having said that, I think there are many people, murderers and others, who make the world worse for their presence in it. By that standard, we should execute people by the truckload, starting with the heads of the world's dictatorships.
Protestantism—seems to increase the divide. At 67 percent in favor, white evangelical Protestants are more likely than any other group to support the death penalty, followed closely by white mainline Protestants (64 percent). Catholics are the least likely among religious whites to support capital punishment, though 59 percent are still in favor. On the other end, religious blacks and Latinos are even less likely than their peers to support the death penalty.
To me, capital punishment is a form of societal self-defense and can be a strong deterrent to crime.
