“Darkness cannot drive out Darkness, only light can do that”. Hades is Malevolent because he tried to take away Hercules strength. He also tried to hurt the girl.
Hades Is described as the god of the underworld.
First, Hates shows he is malevolent to the people because he tried to hurt Hercules. In the website it states how hades is trying to hurt Hercules by taking all of his strength away so he cant save the people and the village. This means that if Hercules doesn’t have any strength then he can’t save all of the villages from all of the huge monsters.
Next, Hades promised Hercules that if he shook his hand he would get the girl back. But instead Hercules lost all of his strength so he couldn’t save the world.
