@Ken4553 Let's be fair, Leslie is a Child. A child who's very clearly been abused and mistreated and Salvatores are pretty good people by nature. Humans are wired to care for and sympathize with children, a pitiful child like Leslie in particular. It's perfectly natural for them to sympathize...
@greatninja3
I think it's a similar issue as with One Piece and Marines. We get the POV of the most sympathetic and nice mage around just like Straw Hats are nicest pirates around. But all the other mages/pirates are more or less evil and the ones opposing them while seen as antagonists by us...
