No government action implicates raw emotion more than a president pardoning a family member.

Seen from a human perspective, Joe Biden’s decision to pardon his sole surviving son Hunter, whom he has always loved to a fault, is about the most understandable action of his whole presidency.

It would take the superhuman emotional control of a stoic not to save a son from prison — and Joe Biden is no Marcus Aurelius. Bill Clinton and Jimmy Carter each pardoned brothers. Donald Trump pardoned his daughter’s father-in-law (whom he now says he will appoint as ambassador to France). Even Abraham Lincoln pardoned his wife Mary Todd Lincoln’s sister, whose husband had served as a Confederate general.
