there are many things that are much worse than death circumstance-wize. You could be a vessel without a soul from a dementor kiss, all your relatives and friends dead (killed by voldy), not loved by anyone, tortured to insanity by the cruciatus curse....if it werent for friends at school, if i was in neville's shoes...that WOULD be worse than death. hes always compared to his father, parents dont even know him, bad at lessons...its quite sad...
