Answer:
If you want a straightforward answer it was moral conviction. If you want a more loop answer, it was 50/50.
Explanation:
Lincoln always thought slavery was wrong, but the only reason we had it was because it was free labor and they were of different race. The moral part was more of Lincoln's point of view, the economic aspect was the country's point of view. Nobody cared about morals then, it was what was best for the economy, and slavery is what was best. Lincoln didn't want to give them rights to vote or anything, he only wanted to free them from slavery because of his morals.
