Well, you have to remember that she's young. In psychological terms, her id (unfiltered & unconscious desires) is still larger than her superego (acknowledgment of social standards and the emotions of other humans). She will be more inclined to perform actions that benefit her in the short term rather than to consider the ramifications long term for other people. She knows that she is an equal to Ed, and their mother is the figure of authority, so she uses her as a medium through which to express her unconscious selfishness.
