Duty or Friendship Quick Write

It is hard to choose between betraying a duty or friendship. When necessary having to choose between duty and friendship, I would choose friendship, and abandon the duty. After you abandon duty, you can still get another duty and other people to trust you. But if you abandon the friendship, you wouldn't easily get another friendship that you can trust or be trust completely. When having a duty to kill your friend, would you want to kill your friend coldblooded or would you choose to save the friend? If betrayed the duty, you wouldn't be trusted so easily next time, if you betrayed the friend, maybe next there wouldn't be any one that want to be your friend.
