The USA was under assault then, as it is now, and Honest Abe, took extreme measures, and they worked.

He broke the amendment process. There was no possible way that states would willingly vote for the 13th amendment, and using the Army to threaten states to do as Washington DC directed them is not a valid constitutional means of ratifying an amendment.

Then there were the threats and bribes he put forth to do it.

I think breaking the ratification process is defacto breaking the constitution, and Lincoln flat out defied Article IV, section 2.

Considering that Lincoln was dead long before the 13th Amendment was ratified, and seven of ten rebel states didn't vote on it until after he was dead you can't very well blame Lincoln for breaking the ratification process. Well, maybe you can.
