Truth vs Reality
“Everybody has their own Reality. That is their Truth” -- I paraphrased this famous quote from a very talented and wise young man. At a very tender age, a sapling was pressured and implicitly made to realize the harshness of this world. That was his reality. Enduring everlasting obstacles and the carrying stigma of a hated clan - thought to be bound to a bloody fate- this young guy proved how much the REALITY can shape a person no matter the Truth. He eventually succumbed under a false pretense of hatred towards his kin, well , to each his own reality .
Itachi Uchiha, not a Real person but encapsulates more than a real person should and would achieve if they pay heed to their own truth and be true to themselves. Although, as Itachi proved, and by which I only vaguely allude to the genius of the writer and creators, Truth is not often the Reality, unless you just care about your own truth.
