No. The show is childish, and the movie is rather comedic as well. Grandfather has several humorous moments, and while he's definitely more vile and deceitful than other KND villains, I still don't think he's heinous enough to be qualified as pure evil. What's more, he appeared to harbor affection for his older son despite him being the one who took his powers, admiring his tenacity and resolve and even putting him in his will.
