Nope. He had many redeeming qualities and he did indeed make some legislative effort to remove the institution. I just think his own internal biases and uncertainties were his undoing in regards to slavery. He believed blacks were inferior to whites, and he thought they should be emancipated in Africa and that freedmen should colonize there, because doing it on American soil would lead to great social turmoil and violence. From an observational standpoint, he was correct in the latter thought, to his credit. Civil unrest and war broke out after the abolition of slavery.
