...You know what? I'm going to be that guy, he thoroughly deserved it and I had a good schadenfreude imbued chuckle during this scene (I saw the Swedish version btw, don't know if it was portrayed differently in the US). That's not to say that Lisbeth isn't a fucked up individual or that she should be exonerated for her crime, just that the scumbag in question in this particular scenario/context is someone I have no sympathy for and felt they got their comeuppance.
I've watched both versions. In the original she sticks a dildo up his ass, leaves the room until the video she's showing him is over then comes back to tattoo him(I actually thought, "What if he starts to like it?"). In the remake, it's much more graphic, she tattoos him while the video is still going on and the audience barely has time to breathe and take the whole scene in, which adds to the shock value of the scene.
(piece of trivia: both the original and the remake were filmed at the same location)
As for whether it was justified: he wasn't just raping her, he was holding her money hostage.
The justice system is a long and arduous process and, although he would have been revealed as a rapist, she would also have been revealed as a victim, which is the last thing she is. What she did to him was justified revenge, it was quick, it was efficient, it prevents him from ever raping another girl (Hopefully, I haven't read the other books so i don't know if it pans out) and it prevents her from being considered a victim. Although I can't say that it was 100% justified or that I support it, I don't feel sorry for the guy.
