The term "more unrightful" implies something that is even more unjust or improper than usual. Its antonyms, therefore, would be phrases that signify fairness, justice, and rightfulness. These opposites could include "just," "fair," "correct," "righteous," and "equitable." Rather than being "more unrightful," these terms denote principles and actions that are in line with commonly accepted moral standards. By contrasting "more unrightful" with its antonyms, we call attention to a stark difference between actions that are morally reprehensible and those that are laudable. Ultimately, it is important to strive for fairness and justice in all aspects of our lives.
