The word “Hero” is Greek and it means “to protect and serve”. It is someone who would sacrifice his own needs to help others. In psychology terms, according to Freud, the individual consists of three layers. The it, the ego and the superego. The it represents desires and doesn’t care about right or wrong. The superego doesn’t care about anything other than right or wrong. The ego is left in the middle. It has the it telling it what it wants and the superego telling it what it shouldn’t want and the ego must mediate between the two.
