Hephaistos
Quote 1
[Hephaistos, in Demodokos' tale:] '"Father Zeus and all you other blessed immortal gods, come here, to see a ridiculous sight, no seemly matter, how Aphrodite daughter of Zeus forever holds me in little favor, but she loves ruinous Ares because he is handsome, and goes sound on his feet, while I am misshapen from birth, and for this I hold no other responsible but my own father and mother, and I wish they never had got me."' (8.306-312)
We're not sure why the gods expect humans to be loyal when they're obviously not too good at it themselves—talk about making (wo)man in their own image.
