Just watched this myself, and the more stand-out obvious thing that didn’t make sense from a writing standpoint (at all), is >!why didn’t he also shoot Blanc? In fact, once he saw him on the island, why wasn’t he the only one he killed? Benoit was the only one that posed an actual threat, he had no way to defend himself (or to flee), and since Miles clearly knew he killed the sister (especially after seeing the death announcement), why wouldn’t he just shoot Benoit?!<
