Freud believed that, in a truly healthy person, the ego would be stronger than the id and superego so that it could consider the reality of the situation, while both meeting the needs of the id and making sure the superego was not disturbed. In the case of the superego being strongest, a person will be guided by very strict morals, and if the id is strongest, a person will seek pleasure over morality and could end up causing great harm (rape, for example, is when one chooses pleasure-seeking over morality, and is a sign of a strong id).
