Desiree remains a rather vindictive genie, probably due to her own tale of tragedy and being broken hearted. Her wishes reflect this; giving off grave consequences beneath the wishes the people make. It's possible she's merely taking out her anger over her loss onto the people whose wishes she grants. Her love tragedy also gives her a rather low opinion of men; she refuses to let any man touch her unless he wishes it. Sometimes she would use wishes people make to her advantage.
