Confused by scene (spoilers)
I did not understand the gambling house slaughter (ie: starting with zatoichi cutting off the guy's arm). The guy was cheating so Zatoichi chopped the guy's arm off? kind of an overreaction wasn't it? Or was there more to the scene than I'm seeing. Or did Zatoichi think, there's no way to get out of this situation without killing all of them?
Or was this part of his plan to eliminate the Ginzo gang?
