I submit that they didn't view blacks as equal humans, therefore slavery was constitutional. Their mistake was in that belief. What say you to their mistake in thinking States can prohibit and outlaw certain activity and property?
Would it stand to reason that Jim Crow was Constitutional since it was passed into law? How about the the Brady Bill? Because something is enacted is not an indication of Constitutionality.

Were you aware that even Thomas Jefferson had misgivings about slavery even though he owned slaves? He even wrote about it. That's not to excuse his actions. But, I wish I knew why he didn't free them.
Not everyone believed in slavery back then. Some were vehemently opposed to it and denounced it publicly, and were even the recipients of violence because of their opposition. I'd recommend reading Lysander Spooner and Frederic Bastiat for their views on the matter.

I think the decision was a concession made to expediate matters. It was difficult enough getting the states to agree to form a Union. I think they should've tried harder.
