I am not even sure it can be called "instructing.."
I was talking about his previous interactions with her.
@Morris: "Hey I found this thing I'm going to play with. I have no idea what it is." [Hands over picture of a loaded gun]. "That's a gun. It's used for killing. Don't play with it, ever. You can use it once you've been trained." "F*** you!" That's basically the conversation Harry and Kim had.
Kim was one of several people Harry "coached through the difficult period surrounding the discovery of their innate magical talents." Harry had previously taught her "to contain and control her modest magical talents." As we learn in
Proven Guilty, not doing that can be very dangerous.
Was it foreseeable when Harry met Kim that she would come across a loup garou, a ruined greater magical circle, refuse to explain the situation to Harry, ignore his warnings, and get herself killed? No. It was not.
Harry didn't tell her anything she couldn't have figured out from Macfinn. She already knew what the circle was for. To contain Macfinn.
It was foreseeable once she showed him the greater circle that she was messing with something she shouldn't be messing with. At that point, Harry's responsibility is to dissuade her from messing with it anymore. That she lies to him and ignores him isn't his fault. It's hers. If she had told him the truth, he would have helped. Even if Macfinn swore her to secrecy, she could have told Harry enough to let him know what was going on, if not precisely who, without betraying any confidences. Because she lied, it was not foreseeable that she was trying to contain a dangerous entity that was already present. What Harry foresaw was that she was going to try some dangerous summoning. He foresaw that if he didn't tell her how to activate the circle, she wouldn't try. He foresaw that if he did tell her how, and she tried, she would fail and death would likely result.
Maybe Macfinn lied to Kim. But if that's the case, after talking to Harry, she should have run for the hills instead of helping him.
Jim essentially tells you what will happen when Harry ends up locked in with Susan. Molly tells you how, Harry tells you why when he mentions the potion. It's priceless. It's why I love the Dresden Files.
But was it foreseeable that Susan would be pushed to her limits and locked up with Harry after he had been thoroughly tortured in a situation in which he could stop her from just killing him?
Jim's always telegraphing what's going to happen and it's often entirely predictable for the genre savvy reader. That's different from foreseeable from the character's point of view. We're basically told Harry's not dead in the first chapter of
Ghost Story, we know more books are coming, and that the books are most likely Harry's journals. It was easy for us to predict he's going to make it back to the land of the living somehow.
So far, it seems to me that the "Harry is responsible camp" position is that what he's responsible for is not being a hermit who hides himself away from everyone because there isn't a situation in which he can participate in the world and not have negative consequences. "Harry shouldn't have ever helped Kim." "Harry shouldn't have been in a relationship with Susan." I haven't seen any realistic suggestions of what Harry should have done once the dangerous situation became apparent. You can't always talk someone out of doing something dangerous and stupid, and that's not your fault.
