It is the film's chief accomplishment that such a character is not merely an archetype or symbol for either good or evil. Rather, he is compellingly, sympathetically human. Hartley, who is quietly but insistently serious about his work, explains that Henry's roots are indeed in archetype. I think that's what we try to do when we make art and tell stories. It's sort of a precocious method to introduce an archetype, have respect for it, and then force it into a situation where it can't stand.
Henry often risks provoking furious outrage from the audience.
When admitting to Simon that he did jail time for sex with a minor, he is unapologetic about it. He blames the girl. At first, it seems too extreme. Yet it ultimately is critical in explaining Henry's later behavior. But when Henry first says these words, he seems reprehensible.
