If there’s room for a “bad guys” construct to be useful at all, I’m not sure it’s to draw moral validation from the degree of your pessimism and fatalism, the degree to which people characterize you as a downer or a “bad guy.”
Of course the conclusion does make sense: that people respond better to the same facts and tensions presented from a place of constructive effort, optimism, good faith, and good spirits—the old thing about catching more flies with honey than with vinegar, right?
