Questions about the Book of Esther

1. In the Book of Esther we saw the Jews kneeling and bowing to Haman because Ahasuerus had commanded it. Is this permissible?
(In what cases is it permitted?) And how were they not punished for it if it is prohibited.
2. Chazal determined that Mordechai married Esther, so how was she considered a virgin while being sent to marry the king if she was already married to Mordechai? (After all, it is mentioned that she took him as a daughter, and so, and he became the guardian of Hadassah (Esther))
3. How did many of the peoples of the land become Jewish in seconds? After all, it is a process…
4. The fact that Esther is Jewish and marries a Gentile means that her children will be Jewish, but how did she agree to marry a Gentile who was uncircumcised in the first place, and Mordechai recommended it to her? Doesn’t this contradict the education she received? (The Torah mentions the story of Shechem and Dinah, “for she was a disgrace to us”).
5. What do you think is the most likely reason why the scroll was included in the canon of books?
