Judaism insists that Nedarim are very serious. For that reason there is an enormous emphasis on Hatarat Nedarim, a Tefila recited while standing before a Beit Din, especially in the days leading to Yom Kippur, to receive a Heter for any Neder one may have made. There are various instances of a Neder. One instance is doing something three times.
Everybody should act according to his level, but it seems to me that in the light of the obligation created in Shamayim by the three-fold טצ"ץ war, it might be better not to say Hatarat Nedarim. This is especially so because the obligation was created by the Yom Kippur war, by a war that started on Yom Kippur. By not saying Hatarat Nedarim, or Kol Nidrei, you run the risk of serious consequences but you bring the Geula. Again, everbody should act according to his level.
