Plot hole: When Seth's piledriver gives out during the climactic fight, there are many vampires in the background politely keeping their distance while he tries to restart it. Similarly, they ignore him while both his hands are occupied with Sex Machine's whip, even though vampires are running around behind him to no apparent goal. (01:31:35)
From Dusk Till Dawn (1996)
1 plot hole - chronological order
Directed by: Robert Rodriguez
Starring: George Clooney, Harvey Keitel, Salma Hayek, Juliette Lewis, Cheech Marin, Quentin Tarantino, Danny Trejo
Revealing mistake: When George Clooney is talking to Juliette Lewis towards the end of the film, it is painfully obvious that his tattoo has been smudged. (01:40:35)
Trivia: Sex Machine's 'crotch gun' is used in Desperado, which also stars Quentin Tarantino and Danny Trejo (the barkeeper).
Answer: Because he is a sadistic lunatic and he wanted to. He has a lot wrong with his brain, paranoia, psychopathy, hallucinations, sexual predation. Probably more. He is a deeply disturbed individual and killing Gloria gave him pleasure.
