It takes many good deeds to build a good reputation, and only one bad one to lose it.
When you do something bad, you can't sleep.
An ill deede cannot bring honour.
That deed is not well done of which a man must repent, and the reward of which he receives crying and with a tearful face.
Instant Karma is going to get you.
If one good deed in all my life I did, I do repent it from my very soul.
To do wrong is the greatest of evils.
