Isn’t it a little late for that?!
After spending 40 days together atop Har Sinai, Hashem hands Moshe the Luchos, which are simply described as “written by G-d” (Sh’mos 31:18). Just as Moshe finishes packing up and begins to head down, Hashem breaks the terrible news to him: Your people have committed the ultimate betrayal by creating a golden calf! Faithful Moshe stays and davens persistently on behalf of the nation, until Hashem finally relents and agrees to not destroy B’nei Yisrael. Moshe then picks up the Luchos and comes “down to Earth,” where he proceeds to smash them in plain view of the people.
