Ridiculous. Tonegawa is a bastard born and bred. He only kneeled because he was proud and arrogant, and was hoping to gain the favor of the Chairman, by showing him he was tough. He didn't give a damn about Kaiji or his dead pals. Kaiji is just such a good dude he doesn't blame Tonegawa about it, even though he is much to blame. Still, the Chairman was ultimately responsible for the stuff anyway.
