Yes, later Diana stands up to him and disobeys his instruction. But, even there, in doing so, she mimics the lesson she learned from him.
To be clear, in no way am I saying that male mentors are inherently bad; but they are disproportionately over-represented in superhero comics/movies.
*Azzarello talked about the Amazons being top warriors, but he did a rather poor job of actually showing it.
