Warrior's Maniacal Transformation into a Villain

the prompt

Live-action cinematic sequence. Static camera. The warrior kneels in the rain, head down, hands gripping his sword stuck in the mud. Rain pours heavily. Thunder rumbles. Slow zoom in. His shoulders shake—he's either crying or laughing. Cut to close-up of his face as he slowly lifts his head. Rain streams down his face. His eyes are bloodshot. He starts laughing maniacally and says through the laughter: "You want me to be the villain? FINE!" He stands up abruptly, yanking the sword from the ground. Mud flies. Cut to low-angle shot looking up at him as lightning strikes behind him, silhouetting his figure. His hair whips wildly in the wind. He points the sword at the camera and screams: "I'll give you a monster!" His eyes glow bright silver. The camera rapidly zooms into his glowing eye. White flash. Cut to black.
