Larxene and Naminé are not at all alike. They may have the same flaxen hair and blue eyes, the same pale complexion. They may both lack hearts; they may both be Nobodies, but they aren't alike.
Naminé is weak and passive; Larxene is strong. Naminé is soft and yielding; Larxene is hard as steel.
Larxene doesn't pretend to have what she does not. She does not pretend to have compassion, kindness, or empathy.
Or friendship.
Or love.
Most of all, she doesn't wish she had these things.
She doesn't.
Not at all.
Larxene and Naminé are not at all alike.
