Anakin uses anger blindly anyway.
You can change mentality.
You're wrong, Vaapad wouldn't be useless to him if he was calm.
he was calm not in a Yoda or Kenobi calm.
Both Juyo and Vaapad requires the practitioner to be calm and in control
Sorry but wrong. Juyo and Vaapad requires to use Darkside. And Darkside has nothing to do with calm, it's exact oposite. Windu during fight with Sidious was anything but calm.
Anakin's blind anger is what made him so powerful:
"His head has been filled with the smoke from his smothered heart for far too long; it has been the thunder that darkens his mind. On Aargonar, on Jabiim, in the Tusken camp on Tatooine, that smoke had clouded his mind, had blinded him and left him flailing in the dark, a mindless machine of slaughter; but here now, within this ship, this microscopic cell of life in the infinite sterile desert of space, his firewalls have opened so that the terror and the rage are out there, in the fight instead of in his head, and Anakin's mind is clear as a crystal bell."
At that point he didn't care that darkside was consuming him. He didn't try to control his anger like he normally did before. He stopped doubting himself. He completly abandoned all the Jedi dogmas and morals, lost all restraints. He completely gave in to his anger. Pure rage focused at single opponent with single desire to defeat him. Reckless, uncontrolled but immenselly powerful and unstopable.
And with the same state of mind he fought with Kenobi. Single desire to defeat his opponent without caring for anything else.
Now to kill the hype of emotions between Anakin and Mace.
Read what Vaapad is again.
Like I said Anakin uses anger blindly anyway,he (at that time )
couldn't control his anger thus letting Obi Wan cut off his limbs
due to the high ground.
Windu made the same ultimate mistake. He tried to strike down defensless opponent, which is completely against all Jedi principals. Darkside took over Windu and it cost his life as well as completed Anakin's fall to the darkside and made Order 66 happen. Windu is to be blamed as much as Anakin.
In comparison Luke in RotJ refused to strike down defensless opponent and as result lightside prevailed, Anakin was finally redeemed and the balance in the Force restored.
Darkside cannot be defeated by darkside. That's what Windu never understood. No matter how long he tempered with darkside, it gave him greater power but like other Vaapad users it led to his downfall.
if you have the I want to win (mentality )with your strategy and you suddenly start loosing
what do you do? you change your strategy and your state of mind.if you change it to I want to fight (mentality )with your strategy and you suddenly change the
pace or length of the battle or duel by either stalemating or loosing
Love is still an emotion.
he loved the Republic
he loved the Jedi Order.
he uses that to fuel Vaapad.
he loves to fight
he loves to win.
You still don't get it.
Here is scenario.
You fight a guy. Then he says: "SUCK YA MAMA". 🙂
Either you gonna get pissed off and beat crap out of him. Or you will try to control your anger but controlling anger will distract you, break your focus and allow him to beat you up.
Same in SW. Kenobi in PM got enrage at Maul and as result started overwhelming him. Years later Kenobi fought Maul again at first he even tooled Maul but then Maul started taunting him about death of Qui-Gon. Kenobi as experienced Jedi controlled his anger but it completely broke his concentration and as result Maul started tooling him instead.
As you see state of mind is not something you can change, it depends on your personality and experience.
And again. It's not enough just to love something, you need to focus on it. You can't think about multiple things at the same time. Windu can't think about republic and Vaapad simultaniously.
