Answer:
a terrible injustice
bad policy
Explanation:
President Lincoln considered slavery both a terrible injustice, as well as a bad policy. Lincoln believed that slavery was a terrible injustice because he thought that no one deserved to be imprisoned or held hostage without having done something to deserve it, such as committed a crime. He believed that this went against the integrity of human beings.
He also believed that slavery was a bad policy, because it was not good for the economy or for politics. He believed that slavery supported an outdated economic system in the South, which needed to be revitalized. He also believed that the existence of slavery weakened the Union.
