Ah, I see you are inexperienced in the way of online RP. Evil characters are never really evil, they're more "evil". Y'know, lurk in the shadows, rage about how the world has wronged them and they'd like to see it all burn, try to seduce people to the dark side... then the first time they see someone do something actually evil they're all "NO THAT'S TERRIBLE YOU'RE RUINING THIS GAME GTFO! *ragequit*"
She's about as likely to be really evil as a Drow played by a thirteen-year-old whose favorite author's last name begins with "S-" and ends with "-alvatore".
