The meaning of this quote "A leader is best when people barely know he exists; when his work is done, his aim fulfilled, they will say; we did it ourselves" means if the leader is unknown to many people once he has finished or achieved a remarkable goal other people (such as Laozi) can steal the glory and be remembered for something they didn't do.

Pardons tend to be controversial because as they overlay justice decisions the President can use the pardon and offer it for a person in the purpose of fulfilling, or attend his own interest or causes. Taking advantage of pardon for personal benefits.
One actual example of a president’s use of his pardon authority was the pardon granted for Former President Richard Nixon by President Gerald Ford on September 8, 1974 regarding any crimes he could have done in Watergate Scandal.
The pardon legally relates to punishment effects for a crime (if it is offered before a conviction it prevents the penalties and disabilities and if it is after a conviction it removes them).
The emotional issues that those most personally affected by the original crime may have toward the granting of a pardon can be vary.
In the case of Nixon critics claimed the pardon to be a “corrupt bargain” and later this seems to be the cause of peoples rejection of Ford and reason of the President losing the elections of 1976. While for Nixon was a great relive and an import act this pardon Ford gave him.
