light yagami did nothing wrong

Light did a good impact and would have ruled better than mikami, which also wanted to kill the non productive "lazy" people and the "morally weak". I wonder if his punishment would eventually have gone beyond "killing bad apples and killing those in the way of it", in that sense i definitely think that mikami with a death note is more terrifying than light. Yes, the idea of one man having the ultimate power to usher what he deems righteous sounds bad by itself, but not as terrible as it would have been with mikami. Mikami is way worse in his way of judging others than light. It was lucky for the world of death note that the note was picked by light, since he used it in a way most people in the world would have not, he was the most "balanced" in comparison, regardless of his desire to become god-like as kira and represent the human to guide humanity to the next step of progress as society.

Anyway, i think it made sense for light to have killed those in the way during the manga/anime when things started to gradually become harder for him, if he didnt then he would have been caught way sooner, it would be suicide and dumb for him to think "oh, you can catch me guys, you are the good ones, i was just trying to make the world better, arrest and execute me". Killing those in the way is only natural for the sake of making his ultimate goal come to fruition. It makes sense in such a logic as well, because being in the way of justice if a form of bad so it doesnt contradict a righteous categorical judgement.

Light's mistake was to kill penbar and his desire for excitement/thrill, he was in the wrong for having killed raye since it was unnecessary and light could have simply stayed messing up the hours of the deaths and casually just going on with his routine. If it wasnt for his established recklessness, despite his high cautiousness the plot of death note would have ended with hin winning even after he killed lind l tayler, but light would not stand that after being defied and taunted by L

He did let the power go to his head though, imo. If you remember, he had certain people killed that were actually good guys, including L. If he had not went crazy over the power he possessed, I might say differently. But still, he killed innocent people.

Light's initial motivations may have stemmed from a desire to rid the world of evil, but the notion that he “did nothing wrong” overlooks how rapidly and deeply he descended into authoritarianism and moral corruption. The power of the Death Note didn’t just expose the cruelty of the world, it exposed his own capacity for cruelty and control. Yes, the world was flawed, but Light’s solution wasn’t justice. It was judgment without due process, without empathy, and without restraint.

He didn't just target criminals. As soon as someone threatened his authority or questioned his actions like the FBI agents, L, or even innocent civilians, he eliminated them to protect his identity. That’s not reform, that’s tyranny. He didn’t sacrifice himself for a better world, he sacrificed others to build a world that obeyed him. He wanted to be God, not a hero.
