It's just like when people use the Jefferson quote about Tree of LIberty needing blood from time to time, to justify insurrection against the government.
It's super fun to point out that Jefferson said that in a response letter to Washington, because Washington was lamenting about having to lead troops against the farmers in the Whiskey Rebellion.
Jefferson was telling him, "look, dude, sometimes governments have to crush rebellions in order to flourish, and that means those rebels will get killed. If you want this tree we planted to grow, you're gonna have to feed it with their blood."
