what if sasuke killed kabuto after killing orochimaru

[Kirin The Dragon Sage]

he dont have capability to do that. Part 1 Kabuto is kakashi level and kakashi part 1 is stronger than hokage kakashi, meanwhile Kabuto also learning from time skip with oro not just sasuke.

base Kabuto>hebi/taka sasuke,
Rinnegan sasuke > Kabuto
