Why does Sato cut ... [SPOILERS]
... his own fingers off? I realize it's a Yakuza thing, especially in Yakuza movies, ESPECIALLY in U.S. movies involving Yakuza ... BUT
Wasn't Sato's plan to kill all the Yakuza bosses in that building anyway? Why make amends with guys he wants to whack? Why not just whack 'em and then go around claiming he got their permission to keep his fingers before they died. Who's gonna contest it?
