Did the Buddha appear for the sake of the immoral?

Mark 2:17 of the Bible says: > And when Jesus heard it, he said to them, “Those who are well have no > need of a physician, but those who are sick. I came not to call the > righteous, but sinners.” Did the Buddha appear for the sake of "sinners" (the immoral)? Or did the Buddha appear to show the "righteous" (the moral) the way to Nibbana?
