What do you think is the 'Moral of the Story' of Death Note?

I'm sure numerous people have various ideas on that question, but mine is something a little simple: Moral is that, no matter how good the intention is/was, anybody could consume themselves in a great power of controlling death itself, and end either way (good or bad).
-My friend came up with one that goes: Any gift or power can be used for good or evil, abused or praised, it's not destiny that controls those actions, it's our decisions.
But that's just our say in the whole thing. I pag-ibig death Note for being so open when it comes to these tanong ^______^

^I apologize if my answer was long ^^" lol

When I finished Death Note, I actually put a lot of thought into this, and here's what I came up with:
~There is no set "justice" in the world, and the line between "good" and "evil" is blurry. Light wanted to eradicate the criminals in the world, but in doing so he became nothing madami than an heartless murderer. This relates to the death penalty- do we really have the right to kill a criminal, even if it's for a good cause?
~Even sa pamamagitan ng killing off as many criminals as you can, you still can't rid the world of all evil. The world is a dark, dark place, you see.
~Power corrupts. We all knew this already, and Light is just another example. He started out determined to save the world but somewhere along the line, his only goal became to rule over it as a "God." His power went to his head and he became evil and maniacal- he became "Kira."
~If you play God, you will be shot. Multiple times.

I guess there were other things, but I can't remember them at the moment.

I would say, that Death Note shows us how ambition can be corrupted sa pamamagitan ng mankind having power that is far too great for them to possess, and that it is not one's place to pass judgement on whether someone is deserving of death.
So overall, an ambition fueled sa pamamagitan ng a strong lust for power cannot succeed once one's morals and values are deteriorated. So long story short, moral of the story = justice always prevails.

If it has to have one, then it's that you can't make humanity behave sa pamamagitan ng killing the bad guys. I mean, a few months after Light's death, everything went back to normal.

You can't massacre a bunch of people and expect the world to be salvaged.

^ I mean, how stupid is that?

not sure but I'll just post this "Don't touch things that will destory yourself"

one person cant change the world, but everyone toghether can.

i dont really think Death Note had a moral, it was madami enteriment in it than moral.

in my opinion: even though something may seem like a good idea at first, doesn't mean its right......

you cant become 'the god of the world' just sa pamamagitan ng killing, even if the killer's victims are bad

That the world goes on no matter what. If you've seen the finale that takes place a few years later you know what I'm talking about.

Killing is wrong, no matter how one justifies it.
