Pippin:
But by the same token, why should Dumbledore sacrifice Snape
 because it might make students safer when it  might as well
make the situation more dangerous. Forcing  Draco
to fail ahead of discovering what the plan was might prevent 
Draco from threatening  student lives. But no one would know
how he planned to bring DE's into the school. In that scenario, 
Snape would die for not having fulfilled the vow, and the danger 
to students from a DE invasion would have been all the greater, 
since Voldemort could order someone else to complete Draco's task. 
Nor would it get rid of the danger of the amateur attacks that 
Draco might already have launched.

The necklace itself could have been a 'timebomb'. If Draco had
been forced to fail between the time he ordered Rosmerta to obtain it
and the time she gave it to Katie, then Snape would have died and
Katie might have died too, because Snape wasn't around to save her.
