I truly truly hate this chapter and this Ida character.
Why did he save that girl? Based on what I know now of his character, he was just doing his job. He probably didn't think much about the incident. Just routine to him, like finding a lost wallet.
That's fine, but then he started acting like the dirty cop that he was all along. I have been reading comments and reviews and I got the impression that many readers consider him a Dirty Harry type of cop. But to me, he's just dirty.
Let us make some absolutely clear. Ida confessed to his partner that he used the girl (Asuza) as an informant. That's a fact. I don't know how and why she murdered the Yakuza dude, but we shouldn't act all shocked about it. I mean, what did you expect? A Yakuza finding out his mistress was acting as informant for a cop? Did you expect it to end with a spanking and cuddles?
I guess the Yakuza probably went violent and she had no choice but to kill him in self-defense.
But this Ida son-of-a-bitch, the one who was her handler, did not even bother to listen to her and eat her meal for old times sake. Just coolly called the cops on her like she's nothing to him.
W.T.F?
That's not Dirty Harry. That's just Dirty. And low.
I am fine with the idea of an anti-hero. I am, after all, a huge fan of Lee Child's Jack Reacher novels. Reacher kills more than a couple of criminals in every novel. Sometimes in cold blood.
Nevertheless, he is a hero because he has a code. And he never killed anyone who didn't need killing. By the way, he's an ex-cop, that Reacher. Based on what I know of him, I can say with certainty that if he ever sent an someone into a dangerous situation, he would brave hail and storm to save that person. And if the situation ended badly, like his informant accidentally killed a Mafia boss or something, he would help. He definitely would throw the book out of the window and help.
He wouldn't act like a damn dirty cop running away from his responsibilities and condemning a woman to a death sentence.
