Have any of you seen Harry Potter and the Sorcerer's Stone. There was a scene in the movie where Harry is in the Dark Forest and he sees a creature drinking the unicorns' blood. The creature turns to attack Harry but a centaur saves him. The centaur tells him that the blood of an unicorn will save your life even if you are an inch from dying but if you kill such an innocent creature you will have a half life,a cursed life.
