The man is an alive independent organism with the same code of behavior that any other alive organism
Our principal vital aim is the survival for which we tries to reduce, at all time, our vital uncertainty
For this we have selected a vital strategy (proactive, dependent...) from de early age.
Our conscience is our interior light that kick us if our acts move us away from the way marked by the vital selected strategy
If our acts favors the vital strategy of the others it will be qualified by the others as "well", if not it will be qualified as "villain".
