Madara spared Tobirama aswell.
Madara isn't Hashirama. Hashirama said he would eliminate all threats to the village, yet didn't lift a finger against Nazirama. There's a clear cut difference between the two.
Kaguya vs Sasuke - sealed with Teamwork. Kinshiki vs Sasuke round one - Succeeds in obtaining the scroll. Even despite Momo being there for a 2v1. Round 2 - Base Sasuke easily evades him while holding the heiress. Round 3 - Defeats him with some aid from his Kage subordinates.
No excuses.
Kaguya vs Sasuke saved by Sakura and Obito
Kinshiki vs Sasuke- Sasuke got stomled ran away.
Sasuke holding one who will soon forgo the Uchiha name- Shikamaru saved his ass
Round 3 Sasuke jumps in when the Kage he works for are stomping his ass.
Round 4 - can't cut theough Momoshiki who can be injured by Micro rasengan, and gets saved and healed by Naruto.
Round 4B --got stomped while Burrito lands a base Naruto's rasemgan to finish Momoshiti
Urushiki - jobbed to him everytime (was it 3, 4, 5+)
Jigen - stomped in round 1 ran away like he ran away from kinshiki
Ishhiti - pushed his shit in, saved by plot arnour and Burrito not being killed.
That's som serious unrivalled jobbing right there.
