Why would Mordecai be considered cursed?
[Esther 9:3] because the fear of Mordekai had fallen upon them. כִּֽי־נָפַ֥ל פַּֽחַד־מָרְדֳּכַ֖י עֲלֵיהֶֽם | Mordecai became Haman, and was feared by all.
“Arur Haman" and "Baruch Mordechai" both = 502.
The Gemara Megilla 7b : Don't become drunk with power.
Rambam (Megillah v'Chanukah 2:15)
What is the nature of our obligation for this feast? A person should eat meat and prepare as attractive a feast as his means permit. He should drink wine until he becomes intoxicated and falls asleep in a stupor.
Similarly, a person is obligated to send two portions of meat, two other cooked dishes, or two other foods to a friend, as implied by Esther 9:22, "sending portions of food one to another" - i.e., two portions to one friend. Whoever sends portions to many friends is praiseworthy. If one does not have the means to send presents of food to a friend, one should exchange one's meal with him, each one sending the other what they had prepared for the Purim feast and in this way fulfill the mitzvah of sending presents of food to one's friends. ( כֵּיצַד חוֹבַת סְעֵדָּה זוֹ. שֶׁיֹּאכַל בָּשָׂר וִיתַקֵּן סְעֵדָּה נָאָה כְּפִי אֲשֶׁר תִּמְצָא יָדוֹ. וְשׁוֹתֶה יַיִן עַד שֶׁיִּשְׁתַּכֵּר וְיֵרָדֵם בְּשִׁכְרוּתוֹ. וְכֵן חַיָּב אָדָם לִשְׁלֹחַ שְׁתֵּי מְנוֹת בָּשָׂר אוֹ שְׁנֵי מִינֵי תַּבְשִׁיל אוֹ שְׁנֵי מִינֵי אֳכָלִין לַחֲבֵרוֹ שֶׁנֶּאֱמַר (אסתר ט יט) "וּמִשְׁלוֹחַ מָנוֹת אִישׁ לְרֵעֵהוּ", שְׁתֵּי מָנוֹת לְאִישׁ אֶחָד. וְכָל הַמַּרְבֶּה לִשְׁלֹחַ לְרֵעִים מְשֻׁבָּח. וְאִם אֵין לוֹ מַחֲלִיף עִם חֲבֵרוֹ זֶה שׁוֹלֵחַ לְזֶה סְעֵדָּתוֹ וְזֶה שׁוֹלֵחַ לְזֶה סְעֵדָּתוֹ כְּדֵי לְקַיֵּם וּמִשְׁלוֹחַ מָנוֹת אִישׁ לְרֵעֵהוּ )
