The end of Naruto has really made many fans appreciate the effect that Kakashi Hatake has had on the series' main characters. He was there to teach, mold and show them how to be high-level shinobi that Konoha could respect. He not only raised Konoha's next generation but Kakashi overcame devastating tragedies to become the exemplary ninja he is today. Sensei deserves props because:
1. He's A Cold-blooded Assassin 
Everyone around the ninja-world knows this fact: when you see a lightning style chakra and Sharingan, you've met your end. Kakashi shows no mercy.

2. Sensei's Mastered Every Trick In The Book
He's called the 'Copy Ninja' for a reason, and with over 1,000+ jutsus in his arsenal, Kakashi can take on any ninja anytime. Plus if you can use Rasengan AND Chidori you get bonus points in my book.
3. Kakashi's Been A G Since Day 1
The son of the Leaf's White Fang has never been a disappointment as he's been a "genius" since his youth as a part of Team Minato.
Having the 4th Hokage as a teacher will rub off on your skill sets a little bit. Just a little. #YoungKakashi #Dangerous
4. He's Had Every Ninja Rank Possible 
He's been a Chunin, Jonin, an Anbu Black-Ops member AND he even became the Hokage after the 4th Great Ninja War. He's done more in his youth than most ninja do in a lifetime. Don't believe me? Look at Iruka Sensei.
5. Kakashi's Had The Hardest Life. EVER.
His mom died young and his dad committed suicide. His own sensei was killed AND Kakashi had to kill one of his teammates with his bare hands. His life has been anything but easy but he still found peace and kicked plenty of butt. Kakashi's real inspiration.
