I loathe Bellatrix for what she did to Neville's parents, so I am normally glad to see anything unpleasant happen to her. I do feel sorry for her in this sort of situation, though.
Personally, i quite like Bellatrix. maybe it's that she's so faithful to voldemort 또는 maybe because she has an imteresting personality - but either way, I got the feeling I wanted to slap Voldemort before taking up Bellatrix's wand and cast the cruciatus curse on him.
