Megillas Esther 7:6 “And Esther said, a despicable man, this terrible Haman”
“Rabbi Eliezer said, we can learned from here that Esther originally pointed to Achashveirosh when she said, “a despicable man”, immediately an angel came and pushed her hand in the direction of Haman” – (Yalkut Shimoni Esther)
It seems rather crazy, how is it possible that Esther HaMalka ever would have considered pointing at Achashveirosh?! Didn’t she realize that by doing so, she was putting herself and the rest of Klal Yisrael in danger?
Rav Shlomo HaLevi Alkabeitz answers in Manos HaLevi (his work on Megillas Esther) that Esther wanted to give herself up for death.
