I swear to all what is dear to me - if you ever call a character like N, or Taka "villain", I'm gonna come to your house and snap your fucking neck by 360 degrees! 

How come people still cannot get the fact that not everyone who's fighting the main protagonist is villain? Those are antagonists, because they are anti-protagonists; it's THAT simple! 

Not every antagonist is villain. Villain is a creature which commits vile (evil) acts. There are antagonists which aren't villains, like afromentioned N and Taka - they are actually friendly toward MC and, in some cases, create a bond between. But purely because of their association with evil teams and the fact both them and MCs have different, contradictionary goals, they are forced to battle each other. 

But, in the same vein, not every villain is antagonist - some of them are PROTAGONISTS. Perhaps the most known examples are Light Yagami from Death Note, Momonga from Overlord or Frisk/Chara from Genocide Route Undertale. They all commit acts cruel and evil, while having either little to no remorse about their acts, have no actual, tragic or sympathetic reason to act that way, or both. Because of that, they are classified as THE EVIL, despite being the main characters of their journeys. While the main antagonists (in those cases, L and Sans especially) are the defacto heroes - the good guys fighting the bad guys. 

I'm ranting about it, because as writer and creator, I'm getting mad about that cardinal, in my eyes, mistake. I know that people might not know about anti-heroes (characters, usually morally good, doing bad things for noble reasons) or anti-villains (characters doing bad things for causes they believe to be noble, yet those are far more complex than one might think, or the true cause is obscured from their sight), but for Arceus' sake, STOP CALLING NICE, KIND CHARACTERS "VILLAINS"!
