Other Countries' Practices and the Death Penalty

Stuart Buck writes, commenting on the Supreme Court's decision in Roper -- which I mentioned the other day -- invalidating the execution of those who commit capital crimes as juveniles:

So the Court has taken into account the European distaste for using the death penalty on convicted brutal murderers. But, after all, Europeans are not uniformly opposed to all forms of killing. I wonder what the Court might someday make of the fact that the Netherlands sometimes allows terminally ill children to be killed, potentially up to the age of 12? (Perhaps these beliefs can be reconciled: If a terminally ill child manages to commit a brutal murder at age 11, then his or her life must be preserved as long as possible.)
