"There have been communist leaders – and not just ones whose parties failed to come to power – who moderated their zeal for full communisation. They have included individuals who in their private lives would not deliberately hurt a fly. One such was Bukharin, animal lover, mountain walker and painter. But kindly Bukharin did not abjure dictatorship and terror in principle, and he condoned most of the violence perpetrated by the Bolsheviks in the early years of the Soviet state."
