If this is pre-Juubi Madara, he taps out at country level I think and that’s with his perfect susanoo.
Kratos is continent level so he has a massive strength advantage.
They’re both in the same speed range so if Madara gets too cocky and engages him in Base immediately, Kratos is gonna rip him apart. Bloodlusted he lasts longer because he presumably goes perfect susanoo, but he would have to rely more on his genjutsu and hashirama cells to stay alive because his love for close combat is gonna get him killed here.
