Sin is something that bothers your heart

The Prophet said sin is something that bothers your heart and you hate people finding out about. When we do something wrong, it makes us unhappy within. Our soul isn't at peace with our wrongdoing. Don't ignore such feelings. Don't try to justify your actions when your inner voice says you've erred. Your conscience is your guardian. To keep it alive, listen to its voice and act upon it. If you keep ignoring your conscience, you will slowly weaken it. It won't remain strong enough to stop you from evil. Soon a time will come when you'll become insensitive to the voice of your conscience. You will sin easily and won't even have any regret.
