Dexter is not like the usual angels that people see as being portrayed on television. Angels may always seem pure and divine and they are usually portrayed as good and they can never do anything wrong but this might mean that you have not seen Dexter before. Now that you are checking this out right now means that you are aware who Dexter is. Dexter is known as the avenging angel and he did not come only once but he has returned as well. See his wings all drenched in blood as he looks so innocently on another side of the screen.
