Cardinal Richelieu and preemptive pardons

This pre-emptive pardon seems weird, but I do remember the horrible things some Trump peeople said, like Steve Bannon wanting to have Dr. Fauci and Christopher Wray beheaded so he could display their heads on spikes outside the White House.

This pardon thing reminds me of the book The Three Musketeers in which Cardinal Richelieu had given the evil Milady de Winter a letter which was a pre-emptive pardon for all the murders she planned to commit ...

“By my order and for the good of the state, the bearer has done what has been done”

But the Musketeers took the letter from her and used it to pardon themselves for executing her.
