You can’t be serious. Abortion is legal today. It is also wrong. Involuntary servitude, in all parts of the world and at all times, is wrong.
And there we have it: something can be "morally wrong" and still be legal. Remember: We do not have courts of justice. We have courts of law.
And in 1857, under the law, slavery was legal. Period. And that, in a round about way, is what the court in Dred Scott grappled with -- was it legal or no; not was it right or wrong.
I disagree. It is an appropriate punishment for certain crimes, and is allowed for under the 5th Amendment following a trial and due process.
