DR1 AND SDR2 KILLER SPOILERS. 

"Why did you do it...?"

"I did it for my own life!" He screamed, voice hoarse and echoing. "Come on, you gotta help me!" Yet his words fell on deaf ears, dead ears, ears that refuse to listen to this murderer as cold metal met his neck and yanked him backwards.

"I did it for my brother," he muttered, eyes downcast before he allowed Monokuma to take him away. One final look behind his shoulder told him that his other brother was breaking.

"I did it for my dream," she was smiling, hands folded across her chest with elegance. Lies, lies, lies. Why was she lying to her own heart? Her dream... did that belong to her or Taeko Yasuhiro? "I even fooled my own heart."

"I did it for peace," her note read as her body rested upon the bench, face in a peaceful smile with her eyes closed and the poison bottle dropped to the floor.

"I did it for despair!" She was also smiling, hand rested on her hip with the cock of her lips, while red fingernails curved over the button that sat just beside her throne.

"I did it for my mother!" His screams bounced off the walls of the trial room, staring across the room to rest on the white-haired boy with an oddity of a smile, with his hands slid into his pocket, with an easy-going expression. "Where's my mother?!"

"I did it for justice," she had once said, but now as her identity started to crumble, the truth started to lurk and tease at the boundaries of her shadow. "I did it for my young master," she finally admitted, and he screamed.

"I did it for my beloved!" The girl crooned, saliva curling off the corner of her mouth as her hands dug into her hair. "What a pity... you don't know what it's like to be loved... I feel sorry for you." She was still grinning and cooing to herself as she was sent off to her death.

"I did it for no reason," he had lied, the words fluttering off the lips, but his unspoken message shone through like the sun's light through the sky. He had lied, but his unspoken message shone through like the sun's light through the sky. "I did it for everyone."

"Why'd you do it...?"

The girl smiled. "I did it for hope. So did he."
