My Bloody Valentine (1981)

Question: I don't feel it warrants a plot hole because of technicalities (we never explicitly see him in two places at the same time), but don't you think the movie is very misleading about the identity of the killer? Every time we see a kill, the culprit is accounted for in a bit of a sneaky way. Mabel = he is chilling in a car with the others being very close. Murders at the party = he is drunk and morose, but also should be plotting the most elaborate murder. Also, he has no motive at all for how he acts (kills Happy, who is the only one who shows any respect to the killer), and, in fact, he is the one who tells everyone to run away from the party, saving a lot of lives. Just a case of "he's crazy," I guess? Normally, you'd show them having some sort of split personality or something like that to explain a bit of this erratic behaviour.
