I realize that the closure of Yeshivos has a huge negative impact on Haredi Bachurim, many of my friends complain that since the boys came home, they went "out-of-sync", don't wake up to morning prayer, don't daven in Minyan, stopped their daily Gemmorah portion, etc.
In addition, many of them expose themselves to radio, newspapers, and, unfortunately, to the Internet and movies through their friends or their parents' devices.
I completely understand, that in the eyes of Rabbinic leadership the future of the community is at stake, and some of them (Belz and Vizhnitz, for example) proposed to let everybody get infected but allow the Yeshivos to operate as usual.
I understand that this can be attributed to the Sugya of "inciter vs murderer":
רַבִּי שִׁמְעוֹן אוֹמֵר מִנַּיִן שֶׁהַמַּחְטִיא אֶת הָאָדָם יוֹתֵר מִן הַהוֹרְגוֹ, שֶׁהַהוֹרֵג הוֹרֵג בָּעוֹלָם הַזֶּה, וְיֵשׁ לוֹ חֵלֶק לָעוֹלָם הַבָּא, וְהַמַּחְטִיא הוֹרְגוֹ בָּעוֹלָם הַזֶּה וּבָעוֹלָם הַבָּא. Bamidbar_Rabbah.21.4
R. Simeon says, “Whoever causes a person to sin is worse than the one who kills him. Because whoever kills [a person] kills him in this world, but he [still] has a share in the world to come. However, the one who causes him to sin kills him in this world and for the world to come.
With this approach, many elders are risking their lives.
Halachicly speaking, is there a price too high? How lethal the virus should be to allow/abandon this policy?
