Is it because every single time we see her, she has to be showing off as much as her body as possible. Her image seems to be her real priority in life, what isn't dislikeable about that? But evil? I wouldn't say that.
In her music videos signs of the devil pop up like the triangles and goats and other things like that, but I dont personally think she is a devil worshipper and even if she is I LOVE HER& HER MUSIC and wont quit listening to her. (:
