Holmes can't be in two places at once, so either way, Moriarty wins. If Holmes had immediately deduced the truth and gone to the hotel to stop the bomb, he would've stopped the bomb, but Moran would still be on the roof to assassinate Meinhard. Not only did he outmaneuver Holmes (by leaving a trail of false breadcrumbs to trick him into going to the opera instead of the hotel), he had a backup plan in case Holmes caught on. It's just one more example of Moriarty's Chess Master tendencies.He deliberately left little clues to draw Holmes on. But Moriarty wanted to play his game with Holmes and match wits with him. He could have easily - very easily - had Moran set up outside the university and just shot Holmes in the face when he showed up to the university to chat. For Moriarty, its the game of shadows he and Holmes are playing. Also keep in mind that for Moriarty, its not just about his criminal empire or starting World War I.

Moriarty was simply doubling up on his killing to make sure that his target went down.


For the bullet to enter Meinhard so cleanly, he would've had to have been standing up when he was shot. Hoffmanstahl, Moran was essentially a backup plan to guarantee that the target was eliminated if the bomb didn't work out.

Also, Rule of Drama probably applies here.The only reason we don't get this information explicitly in the film is because Watson assumes the role of the viewpoint character from that point, and he hasn't pieced it all together. If Holmes is believed dead, there's nobody to get back at for Moriarty's death, so he's simply playing the long game until he can be sure Moriarty's network is sufficiently dismantled. Seeing Watson reminds Holmes that Moriarty is willing to harm his loved ones just to get to him, and has agents throughout Britain (hell, throughout Europe). Frankly, I think the explanation from the novels still works.I know it follows how it goes down usually in the books and other works but when Sherlock pulls Moriarty down the falls with him, of note is that Watson enters the balcony as Sherlock has Moriarty in a hold, apart from causing an adaptional variance (for once), what was stopping him holding Moriarty for a few seconds so Watson could take him down, remember watson was a soldier, who is behind Moriarty, the only excuse I can find is that if Moriarty survives he may be able to hurt Mr and Mrs Watson, so Sherlock Takes a Third Option.Per wiki policy, Spoilers Off applies here and all spoilers are unmarked.
