All you need is one good guy with a death note to stop a bad guy with a death note

Your turning into a Pikmin, you

Get your facts right. The article makes reference to being "banished to hell" however Death Note makes it explicitly clear that there is only nothingness after death and no heaven or hell.

A society where everyone has a death note is a polite society.

And today it'd work with Twitter handles as well, not just names. Always wondered. What if there are multiple people with that name? Did the intention count when writing that name. Did you have to picture in your mind the person whose name you were writing?

Either everyone dies or no one dies, there is no inbetween.

One of the major problems was that Light Yagami was anonymous. What makes you think everyone having a death note is going to fix society if no one knows who wrote in their book? Death Notes are not akin to gun laws because guns can be traced back to their owner.

Just like atomic bombs

No one would ever give out their real name

Is this a USA gun allegory?
