As we're discussing Harry's moral responsibility, I think it would be useful for me to say where I think that responsibility comes from. One is responsible for the reasonably foreseeable consequences of his actions. Now we can all come up with wild consequences for mundane actions like choosing Restaurant A instead of Restaurant B, but just because we can foresee them doesn't mean they are reasonably foreseeable. A reasonably foreseeable consequence for such a choice is that I always eat things I shouldn't at the first restaurant but not the second, so I will get fat if I keep choosing the first one. It would not be reasonably foreseeable that going to the first restaurant would kick off a gang war because the gangs were having a meeting there and I wore the wrong color or something.
And, as I said, if I knew I am able to conceive and also have issues that could make me lost the control I would take pills, or have an intrauterine device or whatever could work in half-turned
The fear isn't that she is going to lose control and have unprotected sex. It's that she's going to lose control and eat someone. I don't think the specific circumstances that lead to Harry's apartment to become a sex dungeon were foreseeable.
The thing with Kim Delaney was that Harry warned her there was danger in what she was asking, but he didn't tell her why it was dangerous.
But didn't he? He said she couldn't handle the spell at her current level and he would advise against it even if she could handle it because failure could kill a lot of people.
@Morris: I can see saying Harry bears responsibility for not breaking up with Susan after
Fool Moon. Correct me if I'm wrong, but my recollection is that Harry told everyone that he was in charge and they had to listen to him. Harry told her to stay with the van. She ignored him for a story. From that, Harry could have known that Susan would ignore danger she had no business facing to get a story. (That's probably where Bianca got the idea to deliver the invite in front of Susan). Other than that, I don't think there is any reason to say Harry has any responsibility for Susan's actions in
Grave Peril.
Also, I don't think Susan was willing to sleep with Harry for a story. I think she was willing to sleep with Harry, period. I think she was also willing to take abuse their relationship.
As to Kim, Harry didn't give her the greater circle. She copied it from MacFinn's. I'm pretty sure she would have tried it no matter what Harry did. If Harry has any responsibility for that one, I'd say it was instructing her at all, though we don't know enough about her talents to know what the risks of giving her no instruction at all were.
I'd say the responsibility split as between the two of them maxes out at something like 5/95 for Harry/Susan and .01/99.99 for Harry/Kim.
