The CIA did not invent LSD lol what are you on about <| sep |> It doesn ' t really belong here . <| sep |> He became a spy for a few speculative reasons and one we ' re fairly sure of . After Lily and James died , leaving Voldemort would have meant certain death for him , so we can assume this is one of the reasons he chose to stay . The one we know about is that Dumbledore thought Snape would be an invaluable resource to have in Volde ' s camp . Don ' t try and justify his choice . He did it for power and because he wanted to . He would have stayed if it wasn ' t for Lily . <| sep |> Seriously , does anybody give a shit ? This is a message board . <| sep |> jokes on you , we are the meat tubes and there is no god <| sep |> I yelled . at the jehovahs witnesses that knocked on my door at 9 am . It ' s thanksgiving how dare you ! SLAM !
