Chasidut for Pirkei Avot 5:1
בַּעֲשָׂרָה מַאֲמָרוֹת נִבְרָא הָעוֹלָם. וּמַה תַּלְמוּד לוֹמַר, וַהֲלֹא בְמַאֲמָר אֶחָד יָכוֹל לְהִבָּרְאוֹת, אֶלָּא לְהִפָּרַע מִן הָרְשָׁעִים שֶׁמְּאַבְּדִין אֶת הָעוֹלָם שֶׁנִּבְרָא בַעֲשָׂרָה מַאֲמָרוֹת, וְלִתֵּן שָׂכָר טוֹב לַצַּדִּיקִים שֶׁמְּקַיְּמִין אֶת הָעוֹלָם שֶׁנִּבְרָא בַעֲשָׂרָה מַאֲמָרוֹת:
With ten pronouncements (ma'amaroth) the world was created, [nine "And He said," and "In the beginning" is also a pronouncement, viz. (Psalms 33:6): "By the word of the L rd the heavens were made."] What are we hereby being taught? Could it not have been created with one pronouncement? But, [this was stated] to exact punishment of the wicked who destroy the world, which was created with ten pronouncements [For if one destroys one Jewish soul it is as if he destroys an entire world, and the wicked, who in their sins destroy their souls, are reckoned as having destroyed the entire world. (Thus have I found.) And to me it seems that they destroy the world itself, for they incline all of the world to the scale of punishment, so that it is destroyed because of them. "With ten pronouncements": There is no comparison between destroying a work created in one day and (destroying) a work created in many days], and to give goodly reward to the tzaddikim, who sustain the world, which was created with ten pronouncements.

Mareh Yechezkel on Torah
In Midrash Tehillim, it says, “’The beginning of Your words gives light’ (Psalms 119:130) – the beginning of Your words in the Creation was (Genesis 1:3), ‘Let there be light’; From there, ‘You make the fools understand,’ and they will begin with words of Torah” – and Rashi on Psalms cites this midrash. And it appears that his words can be elucidated according to the Mishnah (Avot 5:1), “With ten utterances the world was created, etc.” And see the book, Orchot Tzaddikim, as he explains that the teacher [of this mishnah] had two questions: One is, what was the benefit of having informed us that the world was created with ten utterances? And also, why was it created with ten utterances? And he answered about the first question, that an evildoer should know to be careful not to sin – for his punishment will be great, since he is destroying the world that was created with ten utterances. And about the second question, he answered that it is to give a goodly reward to the righteous. But that itself is difficult – why should the evildoer be punished with a severe punishment? As what does it matter that it was created with ten utterances, was He not able to have created it with one utterance? For if a craftsman makes a utensil in ten days that he could have made in a day, is his payment any greater as a result; and does one who breaks it have to pay any more? Likewise is it difficult – why should the righteous receive any more reward [as a result of this]? And see what he writes.
