Interesting as it is, do we really need round #N of the "Harry was/was not responsible for Kim's/Susan's fate"?
This is a new argument for me, so just one more thing.
Harry has involvement in what happened to both of them due to his refusal to give them enough information to make an informed choice when he had the opportunity. Instead, when Harry refuses to help Kim she assumes Harry's just treating her like an ignorant apprentice and goes ahead with her plan and gets killed for it. If Harry had helped her out would she have gone ahead with it? Probably, and she might or might not have succeeded with his assistance; he might even have gone there personally when he realized what was at stake. We'll never know. But Harry? He insists on playing the "I'm a mysterious wizard, and I won't explain any of the reasoning behind my decisions" card, and it pretty much cost Kim her life. He basically ensured her failure by intentionally holding back information that could have helped. Granted, she was probably feeling pretty good about her skills by that point, had probably succeeded at some difficult things already, and that gave her the sense that she was ready to go up to the next level. Spoiler: She wasn't, and now she'll never be.
With Susan, he had made sure she knew vampires were dangerous, but judging by her actions she clearly had no idea just
how dangerous they could be. Would she still have gone through with her plan if he had sat her down and
made her understand? Something tells me she would, but something also tells me she would have been better prepared at the same time. She's ambitious, not stupid. She was fully convinced her preparations were enough to ensure her safety. She was wrong. Why?
Because she didn't have the necessary information. Both of them had just enough information to get in over their heads but not enough to realize it until it was too late. Why? Because Harry Dresden refused to tell them.
Both of them got where they ended up through their own decisions based on what they
thought they knew. Who had ample opportunity to correct their mistaken assumptions but didn't? Harry Dresden.
Kim even asked him for help, and he refused.I'm not saying Harry's fully responsible, but he definitely had a hand in what happened to them by denying vital information.

Now, about the microfiction.
Seems like Kincaid is telling himself all sorts of things. "It's only a job." Ha, yeah right. He's grown to care for her in his own weird way.
