The Use of the Unforgiveables

I have been reading the posts of the last week with much interest, 
especially those dealing with the great Snape debate. Some have 
argued that Dumbledore would never have wanted Snape to perform the 
AK on him because it is evil and that it would split his soul. If DD 
indeed had told him to do this, it wouldn't be the first time that 
the "good guys" had used one of the unforgiveables.

GOF, Chapter 27, p. 527 (US Edition)
(Sirius speaking to Harry, Ron and Hermione in the cave about Crouch 
Sr.)
"The Aurors were given new powers--powers to kill rather than 
capture, for instance... Crouch fought violence with violence, and 
authorized the use of the Unforgiveable Curses against suspects."

There were people who agreed with this, though it doesn't necessarily 
make it the right thing to do. DD had also given Imposter Moody 
permission to demonstrate these curses for the fourth years in their 
DADA class that year. 
This might not be that important, but it does open up the possibility 
that DD was open to the idea of using the curse if it meant saving 
someone else.
