The villains almost always get their comeuppance in Disney movies. Debates rage on the internet about whether or not Gaston should really be considered the villain in 'Beauty and the Beast,' but we can all at least agree he wasn't the good guy.
When the character meets his untimely end, he seems to experience a premonition of it approaching when tiny skulls appear in his eyes, as if he's had a vision of the grim reaper. That must have been fun for children to think about.
