When it comes to describing personality, 'trait' and 'attribute' have the same basic meaning. Character: mental, moral, and ethical traits. You could say, "running away is against her character." Using "character" suggests she has strong mental fortitude, or she stands up for what she believes in, or she won't back down from a fight, or something like that. Disposition: the mood and affect someone usually displays. People often say, "she has a sunny disposition," meaning she is usually cheerful and smiles a lot.
