I agree, despite worshiping an "evil" god, Shadowheart's Alignment seems closer to neutral. There are some bad things and some good things she supports, and there are some that she dislikes. Worshipping a certain deity isn't exactly the end all be all of alignment, and there seems to be more to her than just her Sharran Worship so we will probably have to wait and see how they deliver on the character hooks they presented before outright declaring she is a bad character.
