Well, the way I would see it is that Blake can rationalize killing certain really bad people who seriously abuse and oppress the Faunus. I can see it starting out with her only killing people who were going to kill her or someone else, but it gradually becomes about the greater good and she just proves to be efficient at it. She would also get positive reinforcement from the White Fang to which she has a close long-standing bond dating back to her early childhood years.

Even with all that there would be guilt over taking another person's life, no matter how bad the person, and then you have to consider all the innocent lives affected by any death. The pull of the White Fang would not be enough to overcome the guilt forever and she gets a little push every time the group's violence escalates. Killing bad people is one thing, but killing random employees is not something she could justify to herself.

At the same time I imagine Adam was not as ruthless as he was when Blake first met him. Just as she would been hardened by her time in the White Fang, so too would Adam and for her to see him showing such disregard for innocent life makes the severity all the more poignant. For Blake it would be like seeing the person she would become if she stayed. Thus leaving would be as much about saving her soul as it would be anything else.
