>>2321610Madoka doesn't fall into despair. She usually spends all of her magic fighting Walpurgis, but again, that witch won't even be born in the first place.
>>2321614Girls use their own powers to make their wish true, but that's something done indirectly. Kyouko never went to enchant the people herself and Sayaka never went to heal Kyosuke's hand (He just suddenly had his hand healed after Sayaka powers were released.) either, their powers were just used to do it. In the same way, Madoka's powers would be used to create the LoC, but she doesn't has to become it herself.
