I think they are ... just differently. :-/
Good and neutral (like Volo and Hag) characters are providing alternatives to get rid of that thing ...
Evil characters are providing chances to use it.
Why would any evil character wanted to get rid of something that is giving him benefits, especialy if he dont need to yet?
I still dont understand why cant we change Race for our hirelings.

Lets us play Githyanki as racist as they trully are!
