Yes even Lincoln. He was brutal with the indigenous Americans just like all his contemporary genociders.
And even on the subject of slavery, he was basically forced into it. He also really hampered radical reconstruction which sought to actually change the power structure, take land from slaveholders and give it to the freedmen… Went way easy on former Confederates and let them slip into (subdued, but still significant) control. He wasn’t as bad as his successor in that regard but he’s no role model. Read “Black Reconstruction in America” by W.E.B. DuBois if you’re interested.
