At this point in time, both Naruto and soon Sasuke are going to understand the meaning of a shinobi.
Here is Naruto understanding it:
Here is Sasuke:
Naruto knows that in order to be a ninja you have to endure the pain of others and losing others. Sasuke on the other hand is suffering the symptom of what Tobirama said. Sasuke does not know how to deal with the loss of his beloved brother because of the chakra affecting him. Now here's my question. If Sasuke somehow manages to deal with the loss of his brother and clan, will he lose his sharingan or gain the rinnegan. I think kishi will make the rinnegan his reward for overcoming this chakra, but then on the other hand he could take the sharingan because that chakra is no longer affecting him. Tell me if you agree or disagree and why!
