I always hear people talk about how great Death Note is so I tried watching it a few years ago and it just made me very uncomfortable the whole time. The show made sure to point out how great things are goin in the world when ever it could, like one point after the time skip it said that wars have stopped(???). At no point did it ever try making a point about how there could be a flaw in the justice system where someone innocent could be in jail and thus a casualty of the MC. Every non “criminal” he kills is someone who could potentially put a stop to his actions and thus comes off as as antagonists that the viewer Shouldn’t feel bad about dying. The whole thing feels like the author thinks that Light is actually a good guy.
He doesn't have to be good. He is better than the current system we have. That isn't an critique of Kira, that is mark against the system. Light is a good guy by the standards of the world we live in. He might actually be a bad guy outside of context but that is a meaningless assessment.
