However, in GoF, Sirius points out that during Voldemort's first reign
of terror, Mr Crouch obtained authorisation for aurors to use
unforgivable curses. He also says that Moody didn't kill unless it was
necessary. Of course, that implies that when it was necessary, Moody did
kill Death Eaters (and possibly others as well). 

So where does that put the dividing line?
