I'm sad for Matahachi even though I didn't give a f about his mother. After all the shit he's done, he finally manned up and confronted it. He accepted that he wasn't strong like Musashi and his mother and decided to take his mother to where it all began and live a simple life. The bond between them was represented beautifully with his mother still accepting his flaws and loving him even after he confessed to all the shit he pulled. Matahachi's making real progress and I believe he can change for the better.
