Elyse: I've been reading this interesting thread and while I've 
really got nothing illuminating to add, I have a couple of questions 
concerning intention in Unforgivable curses.
According to bboyminn, the Avada Kedavra needs 'fuel' which is 
presumably an internal well of evil within yourself.
Neri's hypothesis was that in order to produce a successful AK, you 
need the intention to hurt. I like both ideas and I remember a few 
excellent posts a while back postulating that what makes an AK work 
is the life force you use to overcome your victim's life force.

So my question is, when anybody under Imperius is forced to commit 
murder, what happens? We have canon implications that an AK can be 
cast succesfully by someone who has been Imperiused and has no idea 
of what he/she is doing. 
Karkaroff says Mulciber specialised in the Imperius curse 
and "forced countless people to do horrific things".
Sirius says " Avery wormed his way out of trouble by saying hed been 
acting under the Imperius curse" ; something Malfoy did as well.
My point is, if you do need a certain degree of intention involved 
to cast an AK, if you really have to draw a large amount of fuel 
from the well of evil within, how come people under Imperius are 
able to do so? 

If it is the intention that counts, logically the AK should not 
work, as the caster has no control over his or her own will. It is 
not his will that his victim die, and the AK should malfunction.
If it requires tapping into the well of evil, I dont see how this is 
feasible under Imperius conditions. If you could summon that amount 
of dark anger/hatred/willpower inside you , surely you can throw the 
Imperius off, right? And as for making an evil choice with a Dark 
Curse like AK, how can you do so when you are incapable of free will 
in the first place?

In GoF, Krum is able to Crucio Diggory under Imperius. I doubt he 
chose to do i, and I dont think he had any grudge against Diggory 
for Krum to *want* to hurt him that much. I dont think he got any 
particular pleasure out of watching him suffer either. Yet Bella 
says that these are the particular reqirements for a Crucio to be 
successful.

And as for Unforgivables requiring a powerful bit of magic, Krum 
could Crucio Diggory with apparent ease. Malfoy says Dark Arts are 
actually taught at Durmstrang. Does this mean that the students are 
taught to harness the evil within? Are they actively encouraged to 
choose evil and do they practise the intention to harm as homework?
I think a definitive piece of canon is reqired to define Dark Magic 
and what the creation requires.

Just me wondering here
