Todd is a sociopath pure and simple.
Nothing personal, indeed.
Well, he may be a sociopath but I'm astonished at the amount of people who think he's Gregor Clegane, a two-dimensional killing machine who only kills for personal, sadistic pleasure. It's pretty clear to me that while Todd has no qualms about ending someone else's life, he's someone who does it because he's desperate for the approval of some authority figure who can tell him that he did well. He killed the kid because he thought it would show him as being responsible and reliable to his superiors. Same reason for Andrea, just different superiors. He only decides to help kill Walt once he figures out it would have Lydia's consent. Uncle Jack, Walt, Lydia, hell, even Jesse when he brings him ice cream. He doesn't give a fuck if Jesse eats ice cream; he just wants approval from someone, acknowledgement that he's not such a bad guy. Doesn't make him a nice person, but it's more characterization and humanizing qualities than any of the other Nazis are given, who ARE just caricatures there to get gunned down in finale and probably Breaking Bad's weakest characters overall for precisely that reason.
Hank is callous about Jesse, true, in a way a lot of people in law enforcement become callous.
And that makes it any less disgusting that he doesn't care if Jesse gets killed in a situation Hank put him in so long as they capture it on video camera?
But as he sees it Jesse arrived at that point because of his own choices, not anything Hank did, nor was Hank forcing him to do anything.
Sounds like pretty Walt-esque justification.
Hank's and Gomie's deaths and Jesse's imprisonment are a direct result of Walter White's criminality, vengefulness, ego and greed. Hank reacted to that, and it can indeed be said that his reaction was wrong. But it was a reaction, not the cause.
ANY situation in Breaking Bad could be broken down to "reacting" to the fucked up, chaotic world they live in, be it Hank in a situation of Walt's making or Walt in a situation of Gus's or whatever. It's what choices they make IN those situations that matters; I'm not going to give someone a free pass for reaction because all action is reaction, especially in a cluterfuck of a world like the black market drug trade.
Hank
chose not to tell the DEA about Walt. Hank
chose to go after Walt personally. Hank
chose to specifically use Walt's vulnerable points, Jesse and the money. And it was only after those vulnerable points were threatened that Walt was backed far enough into the corner that he called the Nazis. Again, no one saying Hank is Walt 2.0, but I think it's similarly disingenuous to remove all culpability and blame from Hank's deliberate decisions, knowing the consequences could be bad for himself and the people he cares about. Like Hank, Jesse, Gus, and everyone else, Hank
chose to go deeper into the city of fire and like the rest, got burned.
