Who is the darkest Greek god?

I'm curious to know, who among the pantheon of Greek gods is considered to be the darkest? Is it Hades, the ruler of the Underworld, with his association with death and the afterlife? Or could it be Zeus, who while powerful and commanding, is also known for his wrath and jealousy? Perhaps it's a lesser-known deity with a sinister reputation that truly holds the title of the darkest Greek god. What are your thoughts on this matter?
