This is the "Good is actually secretly evil" argument.Why do people do good acts, though? Why be altruistic? They do it because it makes them feel good to do it. Ultimately, everything, including good, comes down to selfishness. We do it because it makes us feel good to do it. We do it because we don't want X to happen. It's all about us and what we want.
It's the same with evil acts.
Since good boils down at the core to selfishness and being about what we want, unfettered good often tries to force others to be good as well, though punishments, enticements, rules and more. A world where good has won will have too many who want to force others to be good for the sake of society, their immortal souls, or whatever other reason.
What you're describing isn't -good-. It's more like LN trying to make society work better by "Fostering Good" while doing evil.
