Kitzur Ba'al HaTurim
היקום The existence... there are 3 parallel verses in Tanakh: And I wiped out the whole universe. (Gen. 7:23) All existence on earth was blotted out. (Deut. 11:6) and the whole universe at their feet. To say that just as the generation of the flood sinned because of the abundance of favors and wealth that they had, so did a קרח (Korach Tosefta, Sanhedrin XIII, 9, Rab. Bah. 16:1:8) from the abundance of wealth that he had remained and sinned.
Haamek Davar
You have killed the people of Adonoy. The people were not complaining about Korach, Dasan and Aviram. On the contrary, they were happy that they died, as I explained (Devorim 11:6). They were pained about the death of the 250 men, though, and they suspected that Moshe and Aharon invented the advice to offer the incense. If Moshe and Aharon had not given them those instructions, the 250 men would not have done anything before Korach, Dasan and Aviram were swallowed up, and they would have repented. However, in truth all this was done through prophecy as well, as I explained earlier.
Or HaChaim
The best proof for our theory is the fact that Moses is described as trying to placate only Datan and Aviram when he sent messengers to call them for a chat (Numbers 16,12). When they refused to come, Moses even went to look them up (16,25). The reason was that Moses felt that these two were at the bottom of the whole rebellion. Once we accept this, the death of all the people who perished can be attributed to Datan and Aviram. This results in our being able to find some excuse for both Korach and the 250 men who offered the incense. You find that the Torah wrote in Deut.11,6: "and what He has done to Datan and Aviram, the sons of Eliav, how the earth opened its mouth and swallowed them, their houses, and their tents and every living thing which followed them." Moses attributed the entire debacle exclusively to Datan and Aviram. Having explained this, we can now understand the scholar in Sanhedrin 110 who holds that the company of Korach does not qualify for life in the hereafter as referring only to Datan and Aviram. The contrary opinion who holds that Korach and company will enjoy life in the hereafter and who base themselves on Samuel I 2,8 that "G'd lowers people to Sheol and brings them up again," must be understood as referring to Korach and companions exclusive of Datan and Aviram to whom the verse does not apply.
