Stitches will only heal one of them.

Remember, surgical risk exists in every cut:

Rabbi Yosef Shalom Eliashiv, leader of the powerful Lithuanian religious movement, served as godfather at a Jerusalem brit Wednesday but suffered a deep cut to his hand, apparently when the mohel slipped.

Let’s imagine for a moment that the blade missed the rabbi’s hand and caused a deep(er) cut in the boy. Is it hard to believe that wasn’t possible?

The 97-year-old sage received stitches and was declared well. The baby was unharmed.

The last sentence is not correct. The baby was harmed, but only as intended. That’s supposed to make it acceptable. It doesn’t.
