Kevin is highly intelligent, but also cold, manipulative, and lacks conscience and empathy; he is hinted to be a psychopath, though neither the novel nor the film explicitly identifies him as such. However, he is skilled at mimicking emotions he doesn't actually feel, and can be charming enough to get others to give him what he wants, particularly his father.
