If by killing someone you become a murderer, why does stealing somebody else’s euro not make you a thief? Does every action we take able to change our identity completely? it is all a matter of perspective and the way each person interprets different things. you do not need a specific number of days doing voluntary service in order to become a solidary person, the same as you don’t need to commit a certain number of crimes in order to be known as a murderer. it all relies on how people view things and it obviously it depends on the situation. different people might judge you differently for doing something, but in the end what matters is not what you’ve done in the past, because that is already done and you cannot change it anymore. although your past might affect your present, the present is made to correct your error and start all over again. that way, your actions in the past will not be able to affect your future, which in the long run is the most important.
