AK stealing souls

jklb66:"Maybe Avada Kedavra steals a person's essence as well 
as killing them, robbing them of existence even in the afterlife.  
Also, it makes those who use it more powerful, giving it a triple-
whammy against it.  It kills, it steals the victims' sacred 
soul/spirit/whatever, and (as a special extra bonus) it makes the 
murderer more powerful."

Interesting idea. I can see Avada Kedavra stealing someone's essence, 
although I'm not as persuaded that essence helps the murderous caster. 
Wouldn't Cedric's good essence 'damage' Pettigrew, at least from 
Voldemort's point of view?

Clearly there are other ways to kill with a curse. Harry and Ron both 
point wands at people in a threatening way (Black, Pettigrew, 
Lockhart) and they certainly don't know A.K. The people who the wands 
were pointed at certainly felt threatened enough to keep quiet. I've 
thought there's likely a spell that just "punches" somebody hard 
enough in the chest to stop their heart or something like that.

Your point about A.K. being Unforgivable - more so, it seems, than 
other kinds of murder - argues for the soul-stealing idea.

Now, a suggestion: could you put up a profile so we know your name? I 
can't pronounce "jklb66." We like to get on a first-name basis here!
