Could these characters be any more nasty?: Tender is the Night

Could these characters be any more nasty? Dick Diver, traveling at leisure through Europe, in Rome, while sick wife, Nicole, is stuck back at the psychiatric clinic in Zurich with the children and with her own maladies, gets roaring drunk (not totally clear why, probably because of a lingering guilt for the affair he's started with young movie star, Rosemary) and ends up assaulting an innocent guy (cab driver) in the police station - the cops beat him up and haul him to a cell, where he obviously belongs. He manages to get a message out to wife's sister, Baby, who shows up to bail him out. Horrified at his bruised face and general condition, what does she do? I must see the ambassador at once! She shoots off to the embassy, bullies her way inside, wakes the ambassador, threatens him in various ways (We are a powerful family!), he gives her the address of the consulate, which actually handles such matters, she's outraged that nobody's there (it's 6 in the morning), wants the home address of the consul, and so on. One of the notes to this edition of "Tender is the Night" indicates that F. Scott Fitzgerald got into some kind of similar scrape and worked the material through several stories and drafts. So be it. But what is his attitude toward these bullies and idiots? Perhaps he thinks Baby Warren is wrong in the way she tries to help Dick, but if he so it's probably, in his view, because she's inelegant and almost comic in her frenzy - she's not "cool," like Dick, like a true Fitzgerald hero. I don't think he stops for a moment to realize how cruel these people are, how their misbehavior hurts others. In Gatsby, his narrator does refer to the Buchanons as "careless people" and as cruel (a "cruel body," I remember), but by this stage in his writing, or at least in this dangerously close to autobiographical he has lost all perspective.
