This Court repeatedly has recognized that the whole subject of the domestic relations of husband and wife belongs to the laws of the States and not to the laws of the United States.

The death penalty experiment has failed.

What the Court really has refused to recognize is the fundamental interest all individuals have in controlling the nature of their intimate associations.

I am more optimistic though, that this court will eventually conclude that the effort to eliminate arbitrariness while preserving fairness in the infliction of [death] is so plainly doomed to failure that is - and the death penalty - must be abandoned altogether. I may not live to see that day, but I have faith that eventually it will arrive.

The mixing of government and religion can be a threat to free government, even if no one is forced to participate.... When the government puts its imprimatur on a particular religion, it conveys a message of exclusion to all those who do not adhere to the favored beliefs. A government cannot be premised on the belief that all persons are created equal when it asserts that God prefers some.
