Well to be quite frank, you haven't really seen how it's set in stone, so how can you make such a negative statement? Granted, it may sound ludicrous for the most part because of the idea, and you're allowed to make speculation and opinion and whatnot, but nobody really knows exactly how they're going to do it. In other words, no one really knows if the concept is really going to be as "lame" as leaks put it that way. N can be working with Team Plasma as an undercover, or maybe even use Team Plasma to accomplish his goals, who knows?
This guy definitely looks more evil than most of the other guys that are in the previous versions bar Cyrus by a slight margin, but even then, there may be something much darker about N that we don't know until we possibly play the game(or until more spoilers are released, but the game is coming out next month anyway, so we'll probably get the full experience/information then).
