Premise:
From what we have seen with the multiple generations in the Narutoverse, it really is the exact same damn thing with every generation. A guy longs for power, he leaves for power and their best friend tries to stop him. We have Madara longing for power, Hashirama tries to stop him. Orochimaru longs for power, Jiraiya tries to stop him. Sasuke longs for power, Naruto tries to stop him. Even Danzo wanted so much power to surpass Hiruzen and supposedly fought many times. In the end, Danzo still couldn't surpass Hiruzen.
Conclusion:
