Agreed but you're missing the point, which is that the individual might have so believed in Kubrik's art that he wanted to make personal sacrifices in pursuit of that. For all we know (and others undoubtedly know more about the story than I do), this man might have actually been in love Kubrik and wanted nothing more than to be close to what he perceived as "greatness."

I'm not even saying whether I think it's morally right or wrong. Only that it's not hard to imagine the scenario.
