Harry Potter: 16 Most Devastating Deaths Ranked From Worst To Best

15. Bellatrix Lestrange

How she died: Killed in a duel. Who killed her: Molly Weasley Why it is emotional: Bellatrix is probably one of the best villains of the series and although her loyalty to Voldemort is admirable, her ability to reject and forget about what is right in terms of her family was her biggest flaw. By killing Sirius and then Tonks, Lestrange ensured that revenge was inevitable, and her arrogance and masochism led to her downfall. In the end she messed with the wrong Weasley.
