even a child knows "no one" is safe from being corrupted by power
how is that even a point in his favor?
to embody something that everybody know is true, is simply playing a low level game in the world of fiction
and Light wasn't even corrupted
nor he wasn't someone who should've have fall yet did
this man didn't even doubted his f***ed up dream for a sec
this is simply a character with NO depth, he is merely a "function not personality"
humans don't behave that way
I didn't say it's a point in his favour, I just stated that's his story.
The fall from grace happening to Light is what makes the story. Because Light is not your average Joe, he's not meant to be relatable to just about anyone. He's perfect. That's why the story carries weight.
Light isn't designed to be overly human and someone anyone can relate to. He's designed as the pinnacle, as the perfect one, etc.
His depth isn't in warmth, or being relatable, or stuff like that. It's in his character writing, his nuanced plans, how he ticks. He's not an overly emotional guy, and he sees people as pawns and obstacles in his way, nothing more. He's mechanic, precise, has swagger off the charts.
Light did have a slight doubt at first, when he first utilized the Death Note, but overcame it quite quickly, and his goal of eliminating crime can be interpreted as noble, it's just the way he goes about it and the means he uses to do that, that make it different. And that descent from his original goal to just removing anyone in his way is the fall from grace.
Compare say Light and Lelouch. Most would agree that Lelouch was a hero, no? Lelouch also killed people, waged wars, all for the sake of world piece, and his vision came true and he willingly sacrificed himself in the end. He redeemed his 'wrong doings', whilst Light never did. Light planned on ruling the world as long as he is alive and his original goal from just eliminating crime quickly became the goal of him becoming the God of the world.
