Jon Snow is a bit of a psychopath: Kit Harington

Actor Kit Harington says his "Game of Thrones" character Jon Snow is somewhat like a psychopath in a strange manner.
The 30-year-old actor recalls talking to his director Miguel Sapochnik that the Lord Commander of the Night's Watch secretly thrives when he is on a war front, according to The Hollywood Reporter.
"I actually think secretly deep down, he's a bit of a psychopath, weirdly. He looks for violence. In a strange way, and I said this to (Sapochnik) during 'Battle of the Bastards,' I think that in a weird way this could be Jon's natural home, on this battlefield, where he comes to life. For all of his good, he's a violent man," says Harington.

The actor adds Jon's character does not have much to do with happiness.
"I think happiness is a very strange term to associate with Jon. He has a very odd sense of what 'happy' is. It might not be everybody else's 'happy.' I don't know what happiness is for Jon.
