Belated Ki Tissa Divrei Torah

The Seforno addresses the fact that (in Ki Tissa) Moshe hears what the people are doing but only reacts when he sees it.  My initial response is that seeing is believing.  The Seforno says that Moshe thought that he could talk it out with them theologically.  But when he saw them dancing, when he saw their emotional attachment- that's when he was hit hard by where they were at.

The Kli Yakar says that Moshe broke the luchot in order to be "in trouble" together with the Jewish People because he loved them so much and wanted to be in the same boat as them no matter what the consequences.  Rav Aharon Lichtenstein's reaction to this Kli Yakar was to say that the Kili Yakar himself must have had a great love of the Jewish People to think of this explanation.
