It seemed what Roshi had said invoked a rather deep and emotional response in Altair. The man spoke of his past, and how the Marines had attacked his hometown, allegedly unprovoked. He then went on to speak about how Marines killed innocent people, and in the case of Roshi, even a King. However, Roshi was much too wise and old to entertain these types of things. The ''King'' that Roshi had taken down, was a man who had exiled all of his own nation's doctors and forced them to work only for him. He then withheld medical aid from his own citizens, using medicine as a bargaining chip to control them. But, Roshi did not need to explain this to a pirate. King Wapol also perhaps had family that loved him, but that did not excuse his horrendous and evil actions. But that, too, was not something that Roshi had to explain to the pirate. Lastly, what had happened to Altair's hometown years ago, was something that Roshi could not verify now. If he let go of every pirate with a story, he would have had to let go of many an evil man. But that, too, was not something Roshi had to explain to the pirate.
Unfortunately, all of the things that Altair was trying to use to excuse his own actions of going around and killing others while shouting at the top of his lungs, welcoming others to pirate life - Roshi had heard before. When Altair concluded, asking Roshi if he would willingly let himself be handcuffed in this situation, Roshi responded.
Sorry but, I would have never found myself in your situation.
Roshi said, once again widening into a fighting stance. With his stance, and the pressure that he exerted, Roshi made it clear that the conversation was over, and he was not interested in the pirate's game of words.
