The correct response is: The Framers did not address the morality of slavery, but rather addressed it as an issue of representation.
During the founding of the nation, the Framers largely sidestepped direct moral evaluations of slavery. Instead, they incorporated slavery into the political framework, most notably through compromises like the Three-Fifths Compromise, which counted enslaved individuals as three-fifths of a person for the purposes of representation in Congress. This reflects a pragmatic approach to managing the political and economic realities of the time rather than a moral stance against slavery.
