This case is mentioned in the Beit Yosef (YD 157):
מעשה ברב אחד ששחט תינוקות הרבה בשעת השמד שירא שיעבירום על דת
It happened that one rabbi slaughtered many children in a time of persecution for he feared they would leave the religion
See there for discussion of other rabbis who disagreed and for each side's reasoning.
Perhaps this is the intention of the Kinah recited during Tisha Ba'av, which discuses this time period:
Kinah 22 (Ashkenaz)
אֲבָל אָזְרוּ גְּבוּרָה יְתֵרָה לַהֲלוֹם רֺאשׁ וְלִקְרוֹץ שֶׁדְרָה וְאֵלֵימוֹ דִּבְּרוּ בַּאֲמִירָה לֹא זָכִינוּ לְגַדֶּלְכֶם לְתּוֹרָה נַקְרִיבְכֶם כְּעוֹלָה וְהַקְטָרָה וְנִזְכֶּה עִמָּכֶם לְאוֹרָה הַצְּפוּנָה מֵעֵין כֺּל ...

In his Commentary on the Mishnah, Introduction to Perek Chelek ...
Rambam provides a simple, practical reason:
Guide for the Perplexed 3:36
It is also evident that the precepts which exhort and command us to learn and to teach are useful; for without wisdom there cannot be any good act or any true knowledge.
It’s important to note, that despite the Lubavitcher Rebbe’s indisputably vast command of Jewish sources, the rebbe himself acknowledged that had no explicit proof for his thesis. This makes it almost futile to look for alleged “sources”, when the rebbe himself admitted that he had no parallel source that he could point to.
