I’m surprised by just how fast Light is losing grip on reality. In only this second episode he coldly considers killing his family if they were ever to piece together his part in the (now world famous) mass-murdering case, while later he shows no signs of regret upon murdering (using the Death Note, obviously) a then “police detective” who is threatening him via a TV broadcast. At this moment Light loses any perceived sense of neutral justice and edges closer to outright abuse of power, killing not for the good of the human race, but merely for himself and his own twisted ideals.
Despite Light gradually growing insane, the convoluted brilliance of Death Note is in not knowing whether to cheer for or to boo at our new age dictator; he may be an idealistic bastard, but the hard truth of the matter is that he is arguably doing mankind a great favour by killing off line after line of unrepentant murderers, raining down an ultimate judgement on those criminals protected behind years of lawful bureaucracy. The issue is complex, but ultimately comes down to whether or not you feel everyone, no matter what they have done, deserves a second chance, or if murder deserves murder in return. Both ideals are paved with contradictions. There is no right answer, merely point of view. Light can make mistakes; he will kill innocent people, but does the end ultimately justify the means? Is a better world worth a few innocent lives?
As if to comment on the herd like mentality of human nature, Light pokes fun at the cult websites springing up around his mysterious murdering sprees, and even goes so far as to dub his online followers cowards; suggesting these are people unable to support his methods in public, so they turn to the safe annoniminity of the internet. Knowingly though, Light is himself hiding behind a notebook, only capable of doing the “right thing” behind a locked door.
