People are not monsters
Monsters are zombies, vampires, werwolves and demons. They are creatures of the night whose sole purpose is to inflict pain and terror. There are people in this world who are labeled monsters because of the monstrous acts they've committed. To call someone a monster is too simple. This label simultaneously provides an excuse or a justification for their behavior and implies that there is nothing they can do to change. It makes us feel better because it gives a simple explanation for senseless acts. It frees us from the idea of forgiveness and redemption. These are rather complex ideas and I do not mean to say that it is anyones obligation to forgive or to see the humanity in those who have committed atrocities against them. I am simply saying that it is society's obligation to leave room for people to seek change, even if that change occurs behind the bars of a prison cell.
I am a survivor of rape by the hands of a stranger about my father's age. He will be in jail for several years and will always be a registered sex offender. To me, he will always be a villain. To others, he is a son, a husband, a father and a friend. From the background investigation, I can tell I was not his first victim, but I hope that I am his last. Something happened that caused this man immense pain, likely at an early age. He chose to turn that pain toward others. He is responsible for his actions, no doubt, but he also needs help. At this point, I don't care if he is in pain or not, I care about whether or not he chooses to take it out on others. I will never forgive him, but I hope that eventually he will become an asset to society instead of a liability.
People are not monsters, they are just in pain and cope by hurting others. They are sick and need to be given the chance to change. No one is a lost cause, but no one can be helped unless they want to be. This label of monster has surely prevented many from seeking that help.
