Is capital punishment in its final days in America? Are you for or against it?

The United States appears to be one of the last industrialized countries to continue the use of capital punishment. Psychologically, it may reinforce aggression. Economically, it is preposterously expensive. Ethically, it is debatable. As for a deterrent, most crimes are crimes of passion anyway. Perhaps it may give solice to some families, but is that enough to keep it around? What are your opinions?
