* Sir John reveals that he got the curse after getting bitten by a feral wolf boy when he was a young man so how come the curse wasn't passed on to Lawrence or his brother Ben when they were born?
** From the context of his description, I personally assumed that the fatal hunt happened shortly before his wife's death; he only transformed for the first time after returning home, and afterwards he kept himself locked up to try and control himself until the events of Ben's death 'inspired' him to abandon that restraint.
** Plus, there is no indication that the curse is transmitted in that manner.
* Why didn't Aberline kill himself at the end after Lawrence infected him, instead of being doomed to become a werewolf?
** A few reasons; he may not know how the curse is passed on even if he knows the creature's supposed weaknesses, he hasn't exactly had time to consider what might happen to him when Lawrence was still the priority, and would ''anyone'' be eager to leap to suicide as an option when he doesn't know for an absolute fact he will transform?
* All evidence points to the werewolves of this universe being incapable of controlling their actions while wolf-ified, and mostly unable to remember what happened the next morning. Despite their heightened senses, there is no evidence that they can distinguish blood relatives, or that such a distinction would hold any value for them while in that state. It takes a huge effort for [[spoiler:Gwen to break through to Wolfman Lawrence, and it doesn't take. Yet when young Lawrence stumbles on his wolfed-out father, just after the man has failed to recognize his wife and brutally murdered her, his father somehow avoids attacking him.]]
** When I watched the movie I got the very strong impression that the werewolves are perfectly capable of distinguishing targets and controlling their actions. Evidence for this is given when John Talbot becomes a werewolf and kills his wife, but not his son. Later on he does kill one of his sons, quite intentionally, after they had an argument the day before. Everything we learn about John indicates that he positively delights in the rampant murder and destruction he can anonymously cause via his transformations. His son on the other hand only attacks certain kinds of people; those that he hates (the doctors who torture him in the asylum) and those who get in his way or are actively trying to kill him. At several points in the movie he runs away from people he could very easily have killed, such as the entire police blockade in London. At his worst Talbot’s actions are that of an animal suffering extreme sensory overload, blindly lashing out at everything around him with no understanding. On the other end of the spectrum he displays both curiosity and restraint when he meets Gwen in the woods (on every other kill in the movie, neither werewolf has shown any hesitation whatsoever) and seems to have gained a measure of control over himself just before the hunting party show up. If anything, Talbot’s werewolf side acts like the Hulk if the Hulk were a hairy wolf-thing that only transformed at the full moon. His father is more like the Abomination.
** Even if [[spoiler: Sir John]] was acting entirely on instinct, it's not implausible that [[spoiler:he'd spare Lawrence as a child, but not his adult son in a later encounter. An adult might seem to the Beast like a potential threat to be destroyed, whereas a child-victim would be targeted simply as prey. He'd already killed Lawrence's mother, ergo the Beast already had food.]]
* Near the end when Aberline sends one of his men to warn Sir John that Lawrence is coming, he doesn't seem even remotely suspicious towards the old man himself. Despite the fact that he did hear that doctor describing Lawrence's 'ravings' about not only being a lycantrope himself but his father being one as well. Moreover, when Ben's murder (which started it all) happened, Lawrence was far away from Blackmore - sounds like a decent alibi. And in the weeks that follow Lawrence's escape from asylum a 'Hey, the guy's 'I'm a werewolf' delusion turned out to not be a delusion at all. What if the rest of his 'crazy talk' is also true?' thought never crosses Aberline's mind.
** Could be that Aberline was suffering from a case of TheoryTunnelvision; he had become focused on the idea of Lawrence as the problem and didn't consider that Sir John might be the real killer.
** Pragmatism, he is already dealing with one person who knows he knows is a werewolf, best to deal with Lawrence first, then deal with Sir John.
