HE NEEDS TO EAT. And he will not, because he is clearly under stress.
Not eating + aggressive behavior can be the result of stress like you just suggested it!

I just cannot determine what is stressing him out.
Let's see if we can help you do that!

What type of enclosure do you use?
How big is your enclosure?
Is your enclosure in a low traffic area?
What are your temps (cool & warm side)?
What is your humidity?
What type of thermometer/hygrometer do you use (dial,stick,or digital)?
What kind of hides do you provide (log, homemade, cubbyholes etc) and how many do you have?
Are your hides tight (all side touching your BP's body) and identical?
How often do you handle your BP?

The pinkies were alive and squirming around all over.
If you are talking about pinky mice this could be another problem, if this is what you are feeding him, you are underfeeding your BP.
