The dialogue and actions in this scene are pivotal, signifying the tragic downfall of Anakin and the deep bond that is ultimately shattered between the two former allies and friends.
Here's a more polished version of your retelling that maintains the essence of the original scene:
As Obi-Wan Kenobi and Anakin Skywalker concluded their heated duel, the atmosphere crackled with tension. Obi-Wan gained the high ground and called out to Anakin, warning him, "It's over, Anakin! I have the high ground."
Anakin, fueled by reckless ambition and pride, shot back defiantly, "You underestimate my power!"
"Don’t try it, Anakin!" Obi-Wan cautioned, but Anakin was already poised to make a desperate leap. As he jumped, he lost his footing and stumbled onto the rocky surface. In a swift, tragic moment, Obi-Wan was forced to defend himself and severed Anakin’s arm, followed by his legs.
Anakin collapsed, writhing in agony. "You were the Chosen One!" Obi-Wan exclaimed, sorrow etched on his face. "You were to bring balance to the Force, not join the Sith!"
With tremendous effort, Anakin struggled to reach his former mentor despite the pain, desperation in his eyes. Obi-Wan continued, "I can’t let you go. You are my brother, Anakin."
Yet, fate had left him no choice but to take Anakin's lightsaber. "I must do this," Obi-Wan said, torn between duty and the love he held for his fallen brother.
"Help me, Master!" Anakin pleaded, his voice a mixture of pain and desperation.
"I will not help a Sith," Obi-Wan replied, a mixture of resolve and sorrow. "But one day, you will understand."
Anakin's anger erupted, "I hate you!"
"I'm sorry, Anakin. I can’t save you or help you. Goodbye, Anakin," Obi-Wan said, sorrowfully turning away, leaving Anakin alone in his anguish.
"NO!" Anakin cried out, his voice echoing against the desolation of Mustafar, but it was too late — the bond that once united them had irrevocably shattered.
