He wasn't convinced by the loss of life or anything. His Moscow handlers had to explain to him that the radioactive cloud would be bad for Cubans. Heck, the politburo was demanding WWIII from Khrushchev during the Cuban missile crisis.
Today, Russia maintains an openly published first strike policy on what it calles "tactical nukes." Essentially they say they can launch nukes whenever they feel like it and not consider it a MAD violation. So if Putin's conventional troops are losing, he just nukes the opposition. With madmen like Putin running nukes, MAD makes sense. Its the only thing that does.
