You seem to believe that anything Harry does is okay. And I'm okay with it being that way for you. But not so for me.
As a character I understand the rage, but it's the underlying calculation that would scare any reasonable person. I'm trying to understand why Jim wrote it this way, not arguing that Harry should eat electrons on death row.
No, I don't, and if Harry had killed Rudolph it wouldn't have been okay, all I am saying is his reaction was understandable, and actually quite normal. I am not sure what you mean by calculation.
Because he wants Harry to have flaws people can identify with. Of course an emotional person who looses control is terrifying.
Yes, and pushed under the right conditions anyone can lose it.. Michael in The Warrior, the kidnapping and submitting his child to that kind of terror was a bridge too far.. He lost it and would have brutally, coldly, and messily beaten Father Douglas to death if Harry hadn't stopped him. Michael isn't an evil man, on the contrary he is rather a saintly one, but he is capable of being quite brutal if pushed too far.
What makes it difficult is it is hard to argue with the love and the paternal instincts that triggered the violent reaction in Michael, when his child was harmed. Something would be wrong if he didn't feel them, yet at the same time it is wrong to act on what his impulse to harm the man who harmed his child. I guess that is where the saying comes from,"When emotions run high, it is hoped that cooler heads prevail." Michael got lucky, Harry got lucky, both had friends with cool heads who stopped something they'd regret later.
HIS pain, but his empathy is set to zero.
I think you are very wrong there, Harry feels a great deal of empathy. However in the moment that Rudolph killed Murphy, isn't exactly the time where one would feel for Rudolph.. That might come later... Another problem with the story, nothing about why suddenly Rudolph was so after Murphy and Harry. Bradley was even at a loss..
