The Sefer Minchas Erev brings down the Medrash, in which Chazal compare Esther, who ruled over 127 Me’dinos (countries), to Sara who lived for 127 years. He points out that both Sara and Esther were kidnapped by a gentile king. Sara, however, was saved, and was not defiled by Paroh. And in her Zechus, all the women in Mitzrayim preserved their purity, which was one of the reasons we were Zoche to be redeemed from Mitzrayim; in the Zechus of these Tzniyus'dike women. Esther though, was the exact opposite. She was forced to marry Achashverosh who defiled her. It seems confusing why Hashem did not do for her a Ness like for Sara (which may arouse suspicion about her purity). To lift this doubt, Chazal say that Esther and Sara both had the number 127, a clear message from Shamayim that Esther is related to Sara and a continuation of her legacy, and that’s why they both brought about Yeshuos for Klal Yisroel (end quote of Minchas Erev).
Chazal say that Esther was a: יְּר קְּ רֹק ת (she had an ugly greenish complexion). The Gr"a asks how could she be ugly, if the Passuk in the Megila states: יְּפ תַתֹא רַוְּטוֹב תַמ רְּ א הַַבַז that she was beautiful? The Gr"a answers that the trauma of her situation gave her constant Tza'ar (distress) and she became: יְּר קְּ רֹק ת green, yet Hashem made a Ness, and: ו תְּ הִּ יַא סְּ תֽׁ רַנֹשֽׁׂ אתַחֽׁ ןַבְּ עֽׁ ינֽׁיַַ כָלַ רֹא יהַַַָבַ טו gave her tremendous Chen which made everyone like her.
There are fortunate people who are Zoche to lots of Torah and/or Avoda, good Middos and Kedusha, they have a frum background, with lots of love, good Kishronos, good friends, and a happy disposition, with wonderful Rabbeim, etc. But there are plenty underprivileged people who are missing all (or some) of the above. They can be lacking plenty of purity and/or Torah and/or goodness in all areas. They have no Simcha and no Hatzlacha in their lives. However, if they try their best despite their ongoing Peckel, they can become so great, that they can even be a #1 Zechus for Klal Yisroel.
The main thing is to do the best you can, and then you’re top tops. Esther was stuck with the most horrific Tamei situation with a Rasha (Achashverosh). And a worse anti-Semite than Haman! She had to hide for three years, she never asked for all the cosmetics, she refused the gentile food, and she never revealed her background. She did the best she could in order not to fall into the Tum’ah, and she was rewarded by being a #1 heroine of Klal Yisroel: יַ דוֹרַֽׁדוַֹלְַּרוֹת for generations. We can suggest that perhaps her situation was the Tikkun of the Chet: ש נ הֱ נוַּמִּ סְּ עוּדָ תוַֹש לַַ אוֹתוַֹרָ שָ עַַמגילהַיבַא of having pleasure from the feast of that Rasha. She was known for always listening to Mordechai. What was the #1 request of Mordechai that he begged Klal Yisroel? That they should NOT go to the Seuda of Achashverosh. The sin of having pleasure from Seudas Achashverosh caused all their Tzaros. Now we have an Esther, whose very essence is a deep hatred for Treife pleasure. Here she is, the most beautiful in the world, and marries the biggest Melech, yet... Not only does she not appreciate all this fake Ta'avas Olam HaZeh, but she becomes: יְּר קְּ רֹק ת (green) getting physically disformed and in constant pain over her “lovely” Olam HaZeh’dike plight. Her very: תיאוּצִַּמְַּ essence is a war against the concept of Seudas Achashverosh.
