There’s a lot he can do in his anger, but he prefers to hone it with his sense of justice, just so he could say he gives the defendant a fighting chance. He was a soldier after all, and serving is in his blood no matter how his master may treat him. But unlike a servant, fighting is in his blood, too – not the kind that’s reckless and selfish, but the kind that bands together with others who are fighting for the same cause.
This time, he makes himself the cause, and while he can’t say which of them is the strongest, he can say they’re all good at what they do. In this way, he’s a professional, and as such he will not apologise for the work he does.
