It’s been a long time since I read the book and it’s never really discussed in the film, but I can’t see why Lestat hangs around Louis for more than a week, let alone decades (other than being an immortal freeloader). Although the Hamlet routine plays nice on paper, being around a depressed, melodramatic sourpuss filled with equal measure self-doubt and self-hatred would get real old real fast. I have to assume Lestat’s manipulations aren’t out of real malice, they’re out of amusement just to see how far he can push the Faberge egg that Louis is to finally break (at least that’s what I’d do; I’m an asshole too).

At the end of the day, Lestat’s own family feeds him dead blood, slits his throat, and throws him in the swamp. He makes a miraculous return only to almost immediately be set-on-fire. This was before “de-friending” someone on Facebook was the worst thing you could do to a buddy. All for what? Trying to convince those around him maybe you should enjoy who and what you are? To revel in it — because everything else is just angst-ridden bullshit? That’s pretty harsh. But you know what? You keep calling someone “poodle-killer” for a century or two and that shit is gonna come back and bite you in the ass.

Lestat: “Evil is a point of view. God kills indiscriminately and so shall we. For no creatures under God are as we are, none so like him as ourselves.”
