Loaded question is loaded.
Since I can't be bothered reading this entire thread, I'm probably about to say something that has already been said, but I'm answering you nonetheless.
Atheism is not a worldview. Therefore, you cannot tell him he is wrong using tenets of an "atheistic worldview." I suspect that you only want to demonstrate that atheists don't have a right to moral standpoints, but I'm going to truck on here anyway. You could tell him why what he is doing is wrong, how it hurts other people, hurts society and hurts himself. Instead of using dogmatic cliches, try using reason.
All of that being said, you clearly have no idea how simple atheism really is. Beyond a disbelief in deities, atheists are a myriad of other things. In other words, I can believe my breakfast talks to me and that I can see the future and another atheist can believe that we are but specks of sugar in an alien's breakfast and that his wrinkles are maps to another solar system. You cannot apply a "worldview" or moral stereotype to atheism, whether that stereotype is "atheists lack morals" or not.
