Ok. All fair points.
And yes I have lost people close to me. My uncle killed himself aged 36. My cousin died of C.F in her 20's and this year my Nan who helped raise me died of lung cancer. Amongst others. I know it's not fair and believe me, I understand that death is a part of life.
But what I'm gettin at, is that in terms of the plot of HP, DD didn't have to die. It would have made a far more interestin story if he had faked his own death. When I said what is the point, what I meant was, how did it benefit a fictional series? I don't think it did.
