Well, it can potentially have spoilers. Sometimes these comics are designed to give extra background or tease plot points that might be relevant to the game. However, it's not always a straightforward case of spoiling everything.
Hela would likely be more powerful. She is a goddess in the Marvel universe with superhuman strength, the ability to summon weapons, and immortality. Harry Potter, while very powerful in the wizarding world, has limits to his magic. His spells and abilities are mainly within the realm of magic that wizards understand. Hela's powers seem more raw and on a much larger scale compared to Harry's.
Hela isn't Loki's daughter in the comic universe. Their characters have separate origins and roles. There's no established connection of that nature between them.
