We all have to remember that this is a video game. Nothing that happens in video games has any bearing or influence on real life. Millions of people murder villains or even peers (in PVP) environments all across the world in WoW (as mages, rogues, druids, etc.), CoD (as military), Halo, and an innumerable amount of fantasy games that would take a lifetime to summate.
I was kind of confused by the development in the tutoring job but I tried to resist judgment and attribute the scene akin to Stacey's Mom by Fountain of Wayne. It's a well-known story where teens admire and fantasize about their much older and mature teachers, neighbors, mother's of friends, etc. That being said this video game should tread lightly. INAL but that scene operated dangerously close to what could be considered CP. It goes without saying I will hesitate before playing this game anymore because, despite how good this product is, its still just a game and I'm not going to play games that break laws or ride right against the line(s).
