Oh that's a point, Juhani does start of as Dark Side. I had forgotten that.
But in your very first meeting with her, you either redeem her or you don't see her again (*ahem* spoilers). It would be more fitting to have her as a Light Side character.
But I suppose if they are looking for another Dark Side character, she's as likely as Calo Nord.
