Reason 4

"Sakumo Hatake, renowned across the shinobi world as Konoha's White Fang a jōnin and head of Hatake clan."

"Sakumo was a famous and powerful ninja of Konohagakure. His son, Kakashi, proved himself a genius like Sakumo and idolised him, desiring to become just as great a ninja as his father. His wife died when Kakashi was very young."

"At some point in time during his career as a shinobi, Sakumo confronted and killed Sasori's parents, earning Chiyo's hatred."

"Sakumo was hailed as a genius shinobi, and was praised for his talents in the ninja arts even by the likes of Minato Namikaze, the future Fourth Hokage."

"In his prime, Sakumo was a truly powerful shinobi whose skill and fame were said to overshadow even that of the Sannin."

"The mere idea of facing Sakumo brought fear to his enemies, as shown from the reaction of an Iwagakure shinobi who mistook Kakashi for him, despite Kakashi being a child at the time."

"He was also very proficient in kenjutsu, his reputation as "Konoha's White Fang" stemming from his extensive use of the White Light Chakra Sabre, which emitted a streak of white chakra when swung."

"While his son was still in the academy, Sakumo and his team were sent on a mission of great importance to Konoha. When his team-mates' lives were endangered, Sakumo chose to abandon the mission in order to save them."

"The impact of the mission's failure caused Sakumo to be vilified by the Land of Fire, the villagers of Konoha, and even those he had saved. Dishonoured, Sakumo fell into a deep depression, which caused his abilities to suffer as a result. Eventually, he committed suicide, and later was buried in the Konoha Cemetery."

"Sakumo was a very kind and loyal man. He loved his only son dearly, often picking him up at the end of the day after Kakashi was done playing with his friends. Despite his tremendous fame and power as a ninja, he was a very humble man, which made Kakashi truly look up to and idolise him."

"He had a deep devotion to Konoha and an even greater commitment to his allies and loved ones to the point he would put their well-being before anything else; his commitment was so great that he would sacrifice the completion of a mission in order to save his team-mates, which led to him becoming a public figure of hate and ridicule."

"He was also shown to be a perceptive man, noticing Guy's worn-out condition and from that discerned Guy's character, correctly predicting Guy to be a late-bloomer and his future growth as a ninja."

After a long speech, Lou look at Kakashi and said," Do you know what wrong your father did?"

"... My father did nothing wrong..." Kakashi said while trying to hide his expression.

"Your wrong," Lou shook his head.

".... Then tell me.... What he did wrong?"

"First is he never should use his all for a village that will only value force and power and not people."

'..." Third Hokage.

"Second is that he never reap all honor from those war, honor is self harm, it's only show your value and also your potential treat."

"..." Third Hokage.

"Third is he should not do his best and let those ninja die on their own."

"And what do you mean by that!" Third Hokage angry asked.

Lou look at him and said." Do you forget what I said just now? Sakumo died because he save his teammates so why save people who will eventually kill you? Isn't it idiotic? So tell me is there's any wrong about what I said?"

"....." Sarutobi want to answer but there's nothing come up to refuse Lou.

"Fourth is never become a hero because hero is the people who died unjust."

"Is hero is bad?" Kakashi asked.

"He~ your father is a hero bout he killed by the people he protecting, your teacher is a hero but the villager killed him."

Kakashi and everyone look each other from what he said.

"Your wrong Minato died saving the village!" Danzo angry said trying to correct what he said.

"Are you sure? Then how the enemy found the hidden place we're Kushina is going to give birth? If I'm not wrong only the village elders know it, do tell me is there a secret place that easy to find? Or Konoha enemy is smart that they even miraculously find every Senju Clan mission and the secret place?"

Everyone is not a fool, if you can't still find the pattern then you are a fool.
