Uma parte do script:
Padmé: Anakin, I was so worried about you! Obi-Wan... told me terrible things!
Anakin Skywalker: What things?
Padmé: He said... you turned to the Dark Side. That you... killed Younglings!
Anakin Skywalker: Obi-Wan is trying to turn you against me.
Padmé: He cares about us.
Anakin Skywalker: Us?
Padmé: He knows. He wants to help you. Anakin, all I want is your love.
Anakin Skywalker: Love won't save you, Padme. Only my new powers can do that!
Padmé: But at what cost? You're a good person, don't do this!
Anakin Skywalker: I won't lose you the way I lost my mother. I am becoming more powerful than any Jedi has ever dreamed of, and I'm doing it for you. To protect you.
Padmé: Come away with me. Help me raise our child far away. Leave everything else behind while we still can!
Anakin Skywalker: No. Don't you see? We don't have to run away anymore! We no longer have to hide our love for each other. I am more powerful than the Chancellor, I... I can overthrow him! And together, you and I can rule the galaxy! We can make things the way we want them to be!
Padmé: I don't believe what I'm hearing! Obi-Wan was right... you've changed! You have turned to the dark side! You're not Anakin anymore!
Anakin Skywalker: [with a growing angry look and voice] I don't want to hear any more about Obi-Wan. The Jedi turned against me. Don't you turn against me!
Padmé: [crying] Anakin, you're breaking my heart! You're going down a path I cannot follow!
Anakin Skywalker: Because of Obi-Wan?
Padmé: Because of what you've done... what you plan to do! Stop! Stop now... come back... I love you! [Anakin looks beside Padme and sees Obi-Wan standing at the ship's exit overhearing them]
Anakin Skywalker:[enraged and paranoid] Liar! You're with him! You brought him here to kill me!
a parte enfurecida e paranóica define tudo, eu acho.
Obi-Wan Kenobi: You have allowed this dark lord to twist your mind, until now, until now you've become the very thing you swore to destroy.
Anakin Skywalker: Don't lecture me, Obi-Wan! I see through the lies of the Jedi. I do not fear the dark side as you do. I have brought peace, freedom, justice, and security to my new Empire.
Obi-Wan Kenobi: Your new Empire?
Anakin Skywalker: Don't make me kill you.
Obi-Wan Kenobi: Anakin, my allegiance is to the Republic, to democracy.
Anakin Skywalker: If you're not with me, then you're my enemy.
Obi-Wan Kenobi: [realizing that Anakin is consumed by evil and there's no reasoning with him anymore] Only a Sith deals in absolutes.
[draws his lightsaber]
Obi-Wan Kenobi: I will do what I must.
Anakin Skywalker: You will try.
[draws his lightsaber and confronts Obi-Wan]
IMHO, eu acho que porque Palpatine o transformou totalmente no Lado Negro, nublou sua mente, sempre ficou do lado dele etc.
Anakin se sente traído por Obiwan desde que ele estava sob seu controle. Ser "libertado" por Palpatine o faz odiar mais e mais Obiwan. Até o ponto que ele não pode mais separar o Bem do Errado e defini-lo novamente. Isso resulta em Force Choking Padme e, por fim, em todo um aparato de respiração ao perder alguns membros.
EDITAR: Além disso, talvez uma parte da vergonha / tristeza / culpa tenha ocorrido em sua mente, alimentando seu ódio contra qualquer coisa que levasse Padme para longe dele. Assim como o código Jedi. (Tua não se reproduzirá - Jedi)
Assim, resultando em ele estar tão enfurecido e irracional que ele não aceitará nada que Obiwan teria dito a ele. Eu assumo aqui que Obiwan vê / sente isso e não diz nada a Anakin até Anakin começar o Choque de Força Padme.
