Sasuke is my favourite character, and the reason why I read the manga. He's just so amazingly human. Everything he has ever done, you can see a normal man succumbing before loss, pain, torture like he did. Every Uchiha values certain bonds before everyone else. That's one of the other main reason why I love this clan. They value personal factors before idiotic and mentally challenging concepts like nation, patriotism, and jingoism. The fact that they don't care for these means that they are truly evolved human beings, who know the short-sightedness of the masses that cling to them for petty support and the innate and pathetic need to feel the need to belong in a larger group. When you have your blood relations, you don't need nations. That's why I just love Sasuke, a true human, someone who shuns nation, and loves family over all. Best character in the entire manga.
In short, Uchihas are just that awesome.
