A/N: No wonder Light's so screwed up.
Light Yagami had always had a strong sense of justice.
He had been raised with a police officer as father, so it was to be expected. He had been raised with his father telling stories about crimes at the dining room table, when he was home, and his father had always lectured on what was right and what was wrong. What was good and what was evil.
Light had always been fascinated with his father's job. He thought of him as a superhero, someone who caught criminals and made sure that they were punished. His father was good, and the criminals were evil.
His father took him with him to work, and he got to see the police station. The other officers talked and joked with him, and told him stories about the latest criminals they had caught.
And when his father was home in the evenings, Light asked him to tell him a story about good and evil, instead of one of those goodnight stories the other children was told before bed.
Light was very proud of his father, whom he thought killed all the bad in the world.
His father had always taught him that criminals were evil, and the ones who made sure they were punished were good. It was as simple as that.
So, as Light Yagami picked up the death notebook, there was a childish pride in him that screamed that now could he also be good and punish criminals and be like his father. He could save the world from evil, and he would be good.
Because those who punished evil were good.
