Not a word "creul" in Greek language. If you're asking for "cruel" translated into Greek, here it is:
Cruel = ΣΚΛΗΡΟΣ, ΑΝΕΛΕΗΤΟΣ ( = Annihilator ), ΑΡΜΑΓΕΔΔΩΝ (Armageddon, EL AMARGADO* = The embitterer, The provider of bitterness).
*that's the Spanish original expression for "Armageddon".
agamemnon
cruel = σκληρός [skleerOs] cruelty = σκληρότητα [skleerOteeta]
Since the Greek gods were personifications of natural phenomena and based on human nature, all of them had the capacity to be cruel. Some were worse than others, but all of them, at some point, did something we would consider cruel.
They could all be cruel in some capacity. There wasn't a specific "god of cruelty".
