Well how can I explain this?.. your a monster..

This happened because you were experimented on.. except you went wrong.. now you were this blood hungry monster lurking in the shadows..

One day the TF had a mission to capture you.. but.. they didn't think it would go so wrong.

There you are standing with dead bodies around you.. you look kije a normal human being.. but your not. And ghost immediately tried to kill you out of pure anger of all the people you killed.
