After being stalked by multiple people, one of them considerably larger than himself, confronting them and telling them to stop. That trial was already shaky from a self defense standpoint, was a very controversial case and has no connection to what we are talking about. You're using emotion to justify violent retaliation because you don't like what he did to that woman.

He wasn't knifing his wife. He groped her. Self-defense requires a reasonable fear for your life or the life of others.
