Contrary to what popular belief holds, this is exactly what modern adaptations do to ancient Greek myths, which despite all the gruesome acts and events they tell, were surprisingly lighthearted. The grotesque demons and horrid monstrosities, the hellish underworld and evil gods (Hades in particular but many others get this treatment such as the over-emphasis on Zeus being a Memetic Rapist) we see in modern movies and video games inspired by Greek mythology are the product of blending the ancient myths with the nightmarish medievaleuropean folklore. Of course, some of this is simple Values Dissonance; for the Greeks, Zeus being a massive, kinda rapey horndog was funny, but to modern Western ears it definitely isn't—although this itself is a relatively recent phenomenon.note Think about it—in 1965, a powerful man chasing women and subtly using his power, wealth, and influence to "encourage" women into having sex with him would have been, if not normal, then certainly unremarkable, with his tendencies the subject of jokes among his underlings and colleagues. Today—there would be no jokes, there would be a sexual harassment suit.
Hades and his underworld are often portrayed as horrifying, ghastly, and generally evil. In reality, the Greek underworld, Erebos, is more like a pleasant inn, and Hades was just a little emotionally unstable. The only commonly-found no-no he did in mythology was kidnapping Persephone, and even then, some variations have Zeus selling her to him.
This tends to go for the other gods as well. Zeus is often thought of only as the god who went around having sex with women. Never mind he often punished evil doers or helped maintain the world. This is true for the other gods who had their petty moments, but were not evil or went around smiting humans for no reason. They usually had a reason even if only slight. They also had moments where they would help people who were beneficial to civilization.
