Jesus never used the word heretic or spread the meme of heresy..
He did warn against sheep pens and false shepards though.. (John ch 10)..

He also didn't come to make a religion but instead a family..
In a family some members are often not too smart..
but they are indeed family..

[Salvation]

What about the last judgment when Christ separates the sheep from the goats.

Yes, Christ constantly made, makes and will make judgments.
