I disagree. People like this will put any of their own gain above their morality. And if we look at this rationally, sure at first that means you will start living comfortable. But if everyone does what you do, the world around you would suck. And I’m sorry, I don’t want the world around me to suck, even if I have to sacrifice some potential gain for that.
And this is why, even as a completely egotistical asshole, your goals should be noble, even if only for your own sake.
And this is also why no one should promote lying if there’s not a damn good reason. This is not a damn good reason.
