Yoda theory.
Why Yoda is screaming when he is fighting? I have to say :
He is using his hate... But His hate for combat ! Because he is pacific and and adept of a philosophy of minimisation (because remember the the end form Metal Gear theory than Yoda is like the end in term of stamina..) And combat are such a waste of energy (for him) and he want to end it quicly (And the ironie of that is that making the combat more demanding....).
Do you agree with this?
