I think it has a love element.

So, yeah, there are a bunch of kids who are being raised to be assassins or something "evil". But #9, the best and the brightest, falls in love with a girl from the outside world. The guy hates himself because he's being raised as a killer and is afraid of what he might become, and at last, he and the chick are discovered, she's killed, he freaks out and murders everyone, then runs off.

I think.

...yeah.
