"I didn't and wouldn't have cared if I did. The man is determined to be unhappy no matter what goes on to him here, I just happened to be the cause that month. Besides, he's caused more than his share of miseries for me."

Maul sounds dismissive of the entire matter. He honestly didn't care all that much what had happened to Anakin. It was only when Ezra had compared him to Sidious that he finally got an inkling of what he'd done. He's been more concerned about how the fallout had affected Obi-Wan and has finally realized doing things to Anakin affects the man he loves quite deeply.
