An interesting moral quandary

I recently heard an interesting story that allows for a discussion of the different positions of those major moral theorists Aristotle, Kant and Mill. So, I will paraphrase:

A crack-addict came upon a couple getting out of their car. He noticed their car had a nice stereo and as they were walking away tried to jimmy the door. The couple came back and the man tried to stop the addict. The addict was suffering from severe withdrawn and pulling out a knife he attacked the couple, killing them both. Breaking the window of the car he grabbed the stereo and ran. Later he was arrested and faced the possibility of 4 consecutive sentences of 25 years to life.

Now it just so happens that this same man, a few years earlier, had come upon a burning building. He heard someone yelling from inside and, without a moments hesitation he rushed in, found a man inside, and dragged the man from the building. Afterwards the rescuer was presented with the "Citizen of the Year" award for his act of heroism. His rational was that he was "a good person".

Now, what would each philosopher have to say about this man (who described himself as "a good person")?
