I don't think it is that different inherently. Harry really has some trouble working up to killing people without doubts. Of course, the issue with his mentor was very different emotionally compared any time he's killed a mortal and was also an act of desperation.
Sure, but he still knows, in his heart of hearts, that he's a killer. That's a large part of what bothers him about it.
I wouldn't think there'd be any doubt in killing someone to save your sister's life (unless you are unusually estranged, perhaps).
Doubt? No. Anger and hatred at the guy trying to do it? God yes. My point was...well, I'll get to that in a moment.
Magic is also about will, so you don't necessarily need to have a whole bunch of hate and emotion built in (that's just a short-cut for some and handy for the emotionally). Doubts are the main obstacle.
True! I'm just saying that, inevitably (unless one is a sociopath, and likely even then...rage is one of the things they
do feel) killing somebody in any situation where you have to use magic to do it is likely to be in some part influenced by rage and hate. I mean, think about it.
I'd think even killing to defend your wife gets you lawbreaker (Harry has it).
Oh, it does. I was saying that, debatably, you shouldn't get it a second time for having to do the same thing
again. But would if you were in a different situation (even if only slightly so, hence the sister reference).
My argument is that whatever is going on with the magic produces a kind of psychic backlash.
So's mine. Sorta, anyway. I'm just explaining
why there's a psychic backlash.
It makes you less human, getting you closer to zero refresh. Also, Dresden might seem really cold now, but you have to bear in mind that in the first book he was pretty gentle overall. He's gotten colder and it's had zero to do with having lawbreaker.
Um, having Counselor or Doctor decreases your Refresh too, but I don't think it makes you less human. It makes you a
certain kind of person, one more bound by their nature, but not less of one.
There's nothing in the books that suggests this is the case though. Molly certainly isn't a fanatic for altering people's brains when she did it. Certainly no more so than someone killing in self-defense with a gun or in the defense of a loved one. There's really no indication that Harry was some sort of fanatic for killing people with magic either, rather he was just traumatized by all the trauma he had been through.
Further go beyond killing. Harry uses fire all the time, but that doesn't make him insanely devoted to fire and hence a pyromaniac. There's something odd at work regarding the rules of magic.
Ah! But I'm not saying they're fanatics per se, I'm saying they need the same level of
belief as a fanatic for magic to work at all. They're as devoted to
magic as a whole as ever any fanatic was to their cause. They have to be. And, by focusing that level of will and belief on something inherently traumatic, psychologically speaking, they've twisted themselves as well as twisting or killing others.
