Hades is never happy because after Kronos was defeated by the Olympians, Hades, Zeus and Poseidon "drew lots" to see who would rule over the parts of the cosmos. Hades unwillingly received the underworld as his domain and as such was not part of the Olympian ruling council. For this he blames Zeus and Poseidon, even though luck could of had Zeus or Poseidon ruling the underworld.
