Wrong again. There is tug of war when the attack is in form of avatar.1. There's no tug of war with Preta Path.
2. Sasuke absorbed 8.5 Bijuu's worth of chakra in a second, Susano'o or not.
3. It doesn't matter if Preta Path is resisted or not. It still works just the same.
Wrong part 2. Sasuke absorbed chakra from a still source and his body cant handle that much of chakra that is why he wrapped it around his susanoo.
Wrong part 3. assumption is not an arguement, talk with evident or next.
