Who Really Killed the Witch King in ROTK??

[The Dread Pirate Roberts]

Hmm. If one masters his fear and perhaps even uses it to his advantage, is he still to be considered afraid?

I must not fear.
Fear is the mind-killer.
Fear is the little-death that brings total obliteration.
I will face my fear.
I will permit it to pass over me and through me.
And when it has gone past I will turn the inner eye to see its path.
Where the fear has gone there will be nothing.
Only I will remain.
