Killing off police officers and FBI agents who fuel global terrorism was a good thing.
Light also put an end to bank fueled wars.
He was the hero of the story, do not let reddit soi boys taint what justice is.
The life of a wicked law enforcement law officer who enforces tyranny is not a life worth living.
Depicted above is L, an FBI/police contact with no sense of good and evil who solves cases just for the thrills.
L is no better than a hedonist serial killer, except that he kills faceless people without care, unlike Light Yagami who takes the time to know who each person he kills is.
