what she means:
That's right. I am Kira. So now... what? Are you going to kill me right here? I'm Kira. And... the god of this new world. In this world, I am the law, and I am the one maintaining order. That is the truth. Now, I am justice. The world's only hope. Are you going to kill me? Is that really the right thing to do? Capturing Kira. That may have been the just thing to do in the past. But now, it's obviously evil. The mentality of the world has changed. Are you sure you want to capture Kira just for your own satisfaction? It's been six years since Kira first appeared. War is a thing of the past, most of the criminals have died, and the world's crime rate has gone down by 70 percent. But... the world is still rotten.
