Note ：If you are amoral, you're not a jerk, you just don't know that what you're doing is wrong. In the 1800s, Robert Louis Stevenson, author of Dr. Jekyll and Mr. Hyde (among other treasures), coined the word amoral to differentiate from immoral. Amoral is generally more descriptive, rather than judgmental:
Immoral is having no morality, being wicked or evil. If you are immoral, you know what society considers right and wrong, yet you do wrong anyway. It's a judgment, no doubt:
