In you case it isn't because your desire for society being better is greater, it's that your desire to see a society YOU favor has a better chance to exist.
Your motivation is your own, and not society's. As is mine, the difference being, I don't delude myself as to it's source and motive.
One of these days you'll see the truth. Everyone does eventually, the only question is how long you'll lie to yourself before that happens.
