This is a classic argument in psychology. Behaviorists believe that, regardless of the purpose or motivation, the how
is more important that the why. This is because the how
is the only observable, concrete data you have. If someone says "I'm trying to save the world" then blows up a preschool, then they are still seen as "evil" even if they are motivated by some sense of justice or "good". In this sense, Morganna is driven by revenge and an intense hate as well as fighting for a paradigm shift against the oppressive angels, but that wouldn't be what mattered. She fights with dark arts that focus on binding, corruption, and causing pain. In this sense she is "evil". On the other hand, Kayle's fighting style has some damaging skills, but it has equal parts healing and protective qualities. Since she saves her allies, she is seen as more "good". All in all, though, it does come down to a combination of motivations and behaviors. Morganna owns a bakery chain for crying out loud, so I wouldn't call her "evil".
