In Precarious Life, Butler emphasises the tension and contradiction that humans face. She proclaims that this tension is killing. Quoting Levinas, Butler writes, "the face of the other in its precariousness and defenselessness, is for me at once the temptation to kill and the call to peace, the 'You shall not kill'" (pg 134). One reason explaining as to why people would do this according to Butler is vulnerability. However, I do believe that some people find others weaknesses and vulnerabilites, I do not think that humans have a temptation to kill. It is not as if when we find out someones vulnerability we seek to eliminate them completely. People do use others vulnerabilities to get ahead of others. An example would be someone witnessing a crime. If the person who has committed a crime establishes that the other person is a "weak" individual, the person who has committed the crime may be able to threaten the person who witnessed the crime into not going to the authorites. Butler goes on to say that the face that prompts the reaction to kill is also the one that makes us refrain from killing. The face she writes, "at once tempts me with murder and prohibits me fromacting upon it..." (135) It is easy for humans to make such choices such as killing when they do not have to look at that person directly. Out of sight out of mind relating to unethical feelings relate. Once you have to look at a person, killing does not seem like the right solution, since that person is like you. When we are looking at someone and they acknowledge us we can relate to them and feel their suffering. The story of the soldier not killing his enemy when he runs into him is an example of this. Soldiers are faced with this dilema everyday. It is a lot easier for a human to kill and not see their target. Looking someone in the face gives that person an identity; therefore, changing our perceptions about them and our ability to do wrong against them.
