Hogwarts Legacy lets you be evil and use Unforgivable Curses
Hogwarts Legacy will let you live out your Harry Potter dreams, and there’s no doubt many will aim to be the best wizard there ever was. Of course, others are already chomping at the bit to cause chaos and stir up trouble. The choice of which path to take is completely up to you.
Hogwarts Legacy allows you to follow a path of good and evil, and a bit unfortunately, it doesn’t seem like you’ll see much of a difference depending on the road you take. In an interview with GamesRadar, lead designer Kelly Murphy notes that there will be some different reactions based on whether you’re good/evil, but there’s no grand changes or morality system to work with.
