The road to hell is paved with good intentions

The road to hell is paved with good intentions is an idiom or proverb.Brown, Marshall. (1905). Wit and humor of well-known quotations, p. 121; excerpt, "The road to hell is paved with good intentions" ... [and it] "is the only place of which we ever heard that is. Generally paving is done with the intention of cheating the city."—Boston Post. It is about the difference between what someone intends to do and the outcome of their actions.  In other words, the consequences of one's actions can be awful and tragic instead of the good intentions that lead one to do them.White, William. (1897).  Notes and queries, Vol. 95, p. 499. This can be the result of poor planning.
