The most important talent for a shinobi is not the numberof jutsu. The important thing is... HAVING THE GUTS TO NEVER GIVE UP.
Masashi KishimotoIn this world, whenever there is light, there are also shadows. As long as the concept of winners exist, there must also be losers. The selfish desire of wanting to maintain peace causes wars and hatred is born to protect love.
Masashi KishimotoBeing hurt inevitably breeds feelings of hatred towards your attacker. But when we hurt others, we have to deal with their hatred for us, and our own feelings of guilt. But knowing what it feels like to be hurt is exactly why we try to be kind to others. That's what makes us human.
