That would be very cruel, when Snape taught this spell to the Dark Lord and then is killed by his own spell. It is cruel enough to be killed by Nagini - but his own spell? He lost temper when Harry used his own spells against the Half-Blood Prince as does Harry's father James. But killed by his own spell - no words for that.
