What Was Light's Main Goal? The Deeper Drive Behind Kira's Mission

Who is Light Yagami and what started it all?

To understand Light’s goal, you gotta know where he came from.
Light Yagami, the high-achieving high schooler turned mass vigilante, is the central figure in the anime and manga series Death Note. One day, bored and disillusioned with the world’s moral decay, he finds a strange notebook — the Death Note — that lets him kill anyone by writing their name. Creepy, right?

But here’s the thing: he doesn’t just go on a killing spree (well, at first). He actually thinks he’s doing something good.

Initial intention: Cleanse the world of evil

At the beginning, Light's goal seems almost... noble? He wants to get rid of criminals. “If I can just eliminate the bad guys,” he thinks, “the world will become a better place.”
And honestly, after a few episodes, part of you might even go, “Hmm, I kinda get it.”

But yeah — that doesn’t last long.

The evolution of Light's goal over time

From justice to god complex

At first, Light calls himself the savior of justice. But slowly, that shifts into something way darker.
He doesn't just want to punish evil — he wants to become the new god of the world. He literally says it out loud more than once: “I will become the god of the new world.”

Boom. That’s the real goal. Not justice, not peace — power, total control, and immortality through fear and dominance.

Losing sight of morality

What’s wild is how fast Light moves from killing murderers to killing anyone who gets in his way. Investigators? Gone. Innocents? Collateral damage. Even people close to him aren’t safe (RIP, Naomi Misora... still hurts).

So yeah — at some point, you’re like, “Hold up, this guy’s not a hero. He’s a full-on villain with a god complex.”

Was Light’s goal ever achievable?

This is a big one. I mean, can you even create a perfect world by killing everyone you label “bad”?
Probably not. For one, who decides who’s good or evil? Light did — unilaterally. No checks, no balance. Just ego.

And eventually, that arrogance catches up with him. He gets outsmarted by Near (ugh, Team L forever) and falls — not just physically, but morally and mentally. By the end, he’s begging, bleeding, and totally exposed.

Did Light really believe in justice?

Now here’s where it gets messy.
Some fans argue Light did want to fix the world. That maybe, deep down, he truly thought he was doing the right thing.
But others say nah — it was always about control. The power of the Death Note just amplified what was already inside him: a brilliant but arrogant kid with zero empathy.

Honestly? Maybe both are true. People are complex like that.

I remember watching the show in college — I was obsessed. One friend even said, “Light’s just a misunderstood genius.” But after rewatching it as an adult... yeah no, dude went full dark side.

Conclusion: So, what was Light's main goal really?

Light Yagami’s main goal, at its core, was to reshape the world under his own rule — first under the banner of justice, then as a self-declared god.
He wanted to be feared, obeyed, remembered — the ultimate authority on right and wrong.

But in chasing that goal, he lost everything. And maybe that’s the real lesson of Death Note: when you put yourself above morality, justice becomes just another word — twisted by whoever's holding the pen.
