What he sees in humans? Yeah he just sees them as cannibals, just kidding. He's perfectly neutral about them unless they ate his brother, since monsters are candies in this universe it's eat or be eaten. But unless you were like Frisk, who is the usual Pacifist unlike Chara he won't probably judge you for being kind. Hey, no hard feelings, he's a candy okay? Kids likes sweets, but if you tried to eat him you'll get a bad time instead.
