That's no different than the typical "good cop/bad cop" routine that presumably really does occur in police stations, since if it's shown on telly and movies, it MUST be true.

It's not against the law, since it's not putting the perp in harm's way, nor is a specific threat being mentioned.

“There were a lot of things he could say. ‘Son of a bitch!’ would have been a good one. Or he could say, ‘Welcome to civilization!’ He could have said, ‘Laugh this one off!’ He might have said, ‘Fetch!’ But he didn’t, because if he had said any of those things then he’d have known that what he had just done was murder.”
Absolutely, and you're proving the point. Vimes knows what he did here was perfectly legal both in AM terms (he was applying AM laws regarding arrest to give Wolfie the chance to surrender) as well as Uberwald terms (where there is no law other than the will of the powerful). Yet, in spite of this, he knows that what he did was, if not murder itself, certainly justifiable homicide. The situation is no different than when cops try to get a deranged killer to surrender, and, when the killer refuses or tries to attack the cops, the cops shoot him full of holes. It's all perfectly legal.
The Vimes of the pre-Jingo books wouldn't have had as much of a moral problem in this situation, since his views about the Law had not evolved to this point. The Vimes of Snuff would have sent WIllikens out to follow Wolfgang and armed him with the same firework.
