From any POD ranging from 1905 onwards make the attempts to collectivize agriculture in the U.S.S.R succesful or at least less deadly.
On the contrary, the Soviet "collectivization" was very successful at accomplishing what the Party wished it to.
Namely, the collectivization destroyed the Soviet peasantry as an independent class, forcing them into industrial proletarian relations of production. Further, it enabled the rationalization of agricultural production and the quick deployment of mechanization to agriculture, which would free up reserve armies of labor to allow industrialization. And last but not least, the requisitioned grain was sold on the world market to acquire hard currency to finance the development of heavy industry in the USSR.
If we judge the collectivization programs based on what the Party actually intended it for, it was a great success. The human cost of collectivization was never something the Party leadership lost sleep over.
