Who is the biggest pervert here? Quilty or Humbert?
I'd say Quilty. Obsessed with teenage girls and orgies. Travels around the country with a "femme fatale" who is probably as sexually obsessed as him but, alas, is aging. Seduces mothers and daughters with "stimulating" talks, plus, he's capable of faking IDs in order to take young girls out of hospitals.
Humbert, yeah, he's a creep and he's pulled into this world of perversion (because everybody in this movie is a pervert, believe me) but remember he's on vacation, he's a foreigner, a transplant of cultures who got obsessed by this intense young beauty of a teenage girl.
