that's because of Christian ethics bleeding into Classical mythology, Hades became associated with Lucifer/Satan.. hence he became malevolent.. Ancient Greeks did not have Satan, all their gods were immoral to some extent and that was part of the reason they were gods.. basically Ancient Greek gods did whatever they wanted.. Zeus was a prime example : even ancient heroes were brutal and not actually good-natured (Hercules was a monster) - when Christian ethics arrived in these societies they were quick to bestow good and evil in these settings, that's why Hercules became a nicer character and beings like Hades became demonic.
