Is the law the only thing that stops you from littering?

So you only do things if there is a specific law that compels you? There is no moral compass?

If laws were loosened up and littering was no longer punishable, would you begin littering? Is hypothetical legal recourse the main thing that would motivate you not to act in a certain way?

I'd love to see anyone get charged for literring in a fast food establishment.
