@SethPhotopoulos: That would be my answer. You see, Bruce Banner and Alex Mercer are scientists that turned monsters by their own experiments, learning how to love in that state, and being hunted down by the military. The difference is that Alex, well as a human, is evil. Well, he just turned an already deadly virus into 10x deadlier, and when Blackwatch is after him, he unleashes it to make everyone die with him. That would make the Blacklight Virus, like Hulk who is resentful of Bruce, becomes resentful of human Alex when he finds out the truth.
