This statement is true. Intentions are different from actions. Your statement here is about intention, not action. Throughout his whole life he almost certainly would have wanted slavery to go away. He did not act upon that desire, though, until he could. And Lincoln acted at the earliest moment he could do so successfully to abolish slavery. We can't make everything perfect immediately. Lincoln had the right intentions his whole life, and acted as soon as he could do so with success.
Let’s really think through your fake claim about Lincoln. If he did not “always” want to abolish slavery, then that means that there was a time in his life when he was absolutely 100% fine with slavery continuing indefinitely. That’s absurd. You’re a liar.
