That's the thing, morality isn't based on what they're capable of doing or even what they've done, but what they're willing to do. They're intention if you like. Anne Maria is not an evil person, and since she saved Jo's life in Backstabbers, I don't think you could convince her to kill a person. Unlike Alejandro who has attempted to murder Owen and Cody.

Izzy might go spaz at times, but she will be shocked by certain levels of evil. A character's morality is ultimately based on whether they think an action is right or not, and based on that will they be willing to do said action.
