There is no ambiguity, Grumpy is clearly shown to be offended when Rick insulted him and became determined to kill him for this reason. He also clearly has a human-like behaviour, for example he let the other protagonists leave during his final fight against Rick because he wanted to kill Rick and only him. Plus, he showed some sadistic expressions (such as evil stares and even evil grin) on several occasions.
