Caustic Burno said:
Lincoln didn't give a hoot about slaves.
"In 1858, Lincoln expressed his opposition to racial equality and asserted the superiority of white people."
Look up his plan for them.
The only reason Lincoln freed the slave was to create a hardship for the south.
He did not have altruistic motivation.
To say that Lincoln didn't give a hoot about slaves isn't really true, just as it's untrue to paint him as a flawless liberator fighting for racial justice. He opposed slavery, but didn't believe abolition was possible without upending the political system and stability of the country. The secession of the South forced his hand.
His views on race evolved over the course of his presidency, and he had a notable friendship with Frederick Douglass, who argued for equality of all races. That friendship and the performance of free blacks in the army did eventually convince Lincoln that black people could be worthy of US citizenship and voting rights.
Like most people, he was neither all good nor all bad, but his ability to lead while learning and keeping an open mind is a rare one.
