I feel like I should have noticed this by now!
You know what I just realised?
Lord Voldemort thought the Elder Wand answered to Severus Snape and killed him, when it really answered to Harry. That mistake led to his downfall when the Elder Wand failed him in the last battle.
Voldemort also thought Snape answered to him when he really answered to Dumbledore. That also contributed to his downfall because Snape made it a point to thwart his plans as often as possible. In as many little ways as possible.
Also, Lord Voldemort is Hitler.
Snape is a more mean-spirited Schindler.
Death Eaters are Nazi’s
And the rest of the world is sane.
