Now it's more understandable, but still very underthought. One no face organization, along with Remnants, help you achieve that goal. A world where discrimination and tasteless rage doesn't exist is utopia btw. There's no way you can eliminate discrimination in socially layered society... And no way you can eliminate human traits. We are humans, not robots. So we are different, have our different rules, emotions, views... And we are highly imperfect. And we change. You cannot just murder people because they are who they are. That is discrimination based on character, which even contradicts your own vision.
And I'll say it again. We have a no face organization that just goes around killing people. This will not go unnoticed and unanswered. Even if the Remnants were rulers of a country, people will rise. They will investigate and if the government doesn't solve things, they will take it into their hand. Groups that are inspired will rise. Groups that want to stop the killing will rise. Unrest will rise. Unrest leads to distrust and revolts. How in the world does unrest contribute to world peace? It doesn't. In fact it does quite the opposite.
Not to mention, this organisation would sooner or later be snuffed out. When you're snuffed out, you'll be driven away by angry mob. You can even be beaten to death. That's their judgement on you, the Killer.
And I could continue even further. Because this project is technically impossible. Human nature won't allow it.
There is also one important thing to say.
If an organization wants to operate on the world scale, then it needs lots of things. Lots of money, lots of people and lots of supplies. Since the organization operates as a no face organization, but is huge and needs lots of money... How will it keep its' secrets? In the real world things don't work like over the internet where everybody is anonymous.
Not to mention, lots of people mean lots of people with different opinions inside. There will be people who will doubt... And sometimes can even betray.
You can work with that idea and change it based on consequences. For example the hero can see the consequences of his actions even between commonsfolk. But as it is, it completely lacks realism.
