I chose this image because I feel it represents the effects of murder, as discussed in "Just Lather, That's All". The story showed how a person's identity can change in an instant, but humanity is hard to alter. We see this in the line "No one deserves to have someone else make the sacrifice of becoming a murderer". The situation of the townspeople is so desperate that for the brief time that the barber has the opportunity to end it, he changes. His desperation alters his identity until his humanity reins back his true self. When identities are altered they are easy to "correct", but humanity rarely changes.  

Even though he pressured by the potential good it can bring as well as the the wishes of the townspeople he lives with, he is hesitant. This is because to commit a murder is to create a permanent change to your identity, like blood on a white sheet; traces always remain no matter how many times it is washed, because murder also affects humanity. The story debates the moral standards between ending a life, even if that life is responsible for the loss of lives of others, and if the pressures of peers is more important than the pressures of morality.
