snape isnt bad because he loved harrys mum and dumbldore told snape to kill him so voldemort would exept him look at harry potter and the dethly hallows part 2 thats where the whole story is duh!!!
I would have jumped in front of Dumbledore with my wand and yelled expeliarmous! Then probably gotten yelled at kwa Dumbledore for putting myself in harms way. (have no Idea how to spell that)
