Maybe he'll kill his parents as a result too.
...Or put a internet poll up that decides whenever or not he kills them.
But only if the poll responders say so!
If 4chan or even anonymous still exists a decade or two from now, it's guaranteed that we'll be hearing about a brutal double murder in the future.
Although, if he's smart and thinking of the big picture, this kid will instead play on
his parents' guilt and embarrassment (if they have any) to milk them for all they are worth.
