What is Loyalty?

What is loyalty? I’d define it as an act of how you treat another person and to treat that person with respect and to be true to your word. I’ve always considered myself to be loyal to my family and friends. I always try to be there for them in a time of need. No matter our past or our differences. I’ve been watching the season DVDs of a show called Terminator: The Sarah Corner Chronicles. It is a great, and addictive, show. It makes me think of a scene in the second Terminator movie where Sarah Corner monologues about how the Terminator would be loyal to John. Never giving up on him. Never not being there. But he is a machine. He is programmed that way. Humans are not. By our very nature, we are selfish creatures. It is the animal in us. We are sure to look out for ourselves, many times at the disregard of how it will make another person feel. Is it wrong to be loyal? Should we only look out for ourselves? How does one learn loyalty? I do not know where I learned its specifically. I’d assume I learned it from my family and how close, yet secluded from the outside world we were. How does one overcome loyalty? To become unloyal? I don’t think I can overcome it. But what if change was needed and loyalty needed to be dismissed? How would I overcome that? I suppose I need to ask myself who I would be betraying… others… or myself?
