Give me the Death Note, I can be trusted to act rationally. The only “undeserving” to end up on it would be people who step through Metro doors and immediately stop, even though there’s people behind them.
More seriously I know the author has said it’s about power corrupting, but if that’s the story he wanted to tell then he should’ve chosen a different protagonist. Its also a silly mantra, we do not live in a Tolkien novel, power isn’t some supernatural force.
Peace be with you
Light was a really, really bad example for that. He was arrogant and contemptuous even before the Death Note. All the Death Note did was remove his inhibitions. In my opinion, people without a conscience are way more easily corrupted by power. That’s why my favorite killer is still Dexter Morgan😄. At least he has a code and knows damn well that he’s an asshole.
