Why makers wanted to show only this? Why it should always have a sad and terrible ending which we can can't even bear. This show literally makes us feel so bad being a human as it always concentrates on the darkest side of human with inhumane scenes. Seriously disappointing and depressing series till date but though the concept and idea execution is exceptional. But still what is the purpose of a story telling when you are deciding that it's gone go so bad that nothing is going to save you and this is how it ends. Any story should give us a sense of hope not just crap of society with a disturbing ending.
