This semester two of the projects that we worked on and completed were based upon the stories of Blade Runner (Do Androids Dream of Electric Sheep) and upon The Watchmen. These stories are both similar and different. They both are about characters who take the law into their own hands and are responsible for the lives and deaths of other characters in the stories.
This character in The Watchmen is seen as having an immensely strong moral compass. So strong that he is willing to sacrifice the peace that is found at the end of the story, just so that the truth can be known. I'm not advocating one position over the other.
Night Owl and The Comedian
We see different versions of morality in the story of The Watchmen as well. The Comedian has a stranger, twisted idea of what is right and what is wrong. He's seen as a mercenary and will do anything to ensure his survival. Though on the other hand his love is also part of what saves the world.
Night Owl is the character that I am able to empathize with the most. He is an academic and he tries to save those who need to be saved. He works to preserve peace. He also doesn't want to harm others in the process of ensuring a better future.
What does this allow us to see in Blade Runner?
Deckard works as a murderer for the police. He kills androids who have run away and broken the treaty that ensures that they stay off of Earth. He is responsible for ensuring that a group of beings (androids are not people) are kept under control. We see the moral turpitude of being a Blade Runner. The androids themselves just want to live, though all that they know to do is what they are programmed to do. Roy kills. Deckard kills too.
