Oh, you’re quite right. Perhaps Quirrel was planning to kill the Auror to make it clear that a break-out had occurred? That way, a full check of the prison would occur and Bella’s replacement would likely be found. Which in turn would mean that it was put there simply to deceive Harry into a false sense of security. When the break in is made public, Dumbledore would naturally come under suspicion (since a Dementor disappeared under his watch) and he would suspect Harry. That might also explain the lack of the 30th charm by Quirrel. Might make Harry traceable.
I could be completely wrong, of course. Pure speculation.
Harry didn’t even consciously try to stop Quirrel’s killing curse. It was an accident. Quirrel couldn’t have counted on it happening to set Harry up.
