He is nicer to her than anyone else... Well keep in mind he is a Goblins not a human and what a Goblins do is what he did it is, like "blaming the lion for eating a sheep". And what did the humans do they abused her lock her up. The people who were "nice to her" are those who made her be like this why didn't the stand out for her. But no all of them agreed to treat her like a monster and locked her up instead of helping her. 😑
