Believe me, I don't call Kurapika insane lightly, I've thought it over. Just think about how many times Melody has to calm him down. His first reaction to seeing the fake spider on Majitani's back. Seeing him after he's collected some of the Kurta clan eyes and him just sitting there in such a statued intense way. Think about how he felt after he was told the Phantom Troupe were found dead (when they were just dolls) during the Yorknew arc. He looked almost upset that he wasn't the one to take revenge. Maybe the fact that he knows what he's doing sometimes doesn't make him full-on crazy, but he's definitely very deranged. Which is understandable :P
