[url=http://fategrandorder.wikia.com/wiki/Who_Am_I]This[/url] CE from /GO hits a really poignant note for me.

"――I am the son of the great King of Knights.
――I am the arrogant Knight of Treachery. 
I am both, and both are myself. 
However when I wear this helmet, I am neither of those
I can only think that I'm just like any other living being 
One that you can find anywhere, worthlessly and frantically trying to stay alive 
So just like they breathed their last breath 
I guess that I will surely perish like they did 
That's why before I meet my last moments, I want to know. 
――Just who the hell was I?"
