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.
Why do you think that’s what you’re doing here? You’ve ignored the material conditions in order to focus on the singular aspect of power as a corrupting force, completely ignoring the context of how they gained power in the first place, a direct indicator of previous corruption. Your claims assumes the corruption happens in a vacuum once they gain power.
