A.you should do your own homework b.abraham lincoln did end slavery but only for the confederacy which obviously wouldn't listen to him since they were rebels. c.he didn't care about slavery he only ended it to preserve the nation as he called it.
What I suggest you should do is try and do some research about him on the internet like Wikipedia, etc. I don't know a lot about Abraham Lincoln, but what I can tell you is that he did not agree with slavery.
