To demonize all Soviet "leaders" at all levels, to portray them as unqualified villains and evildoers, unprincipled self-seeking scoundrels who were indifferent to the interests and needs of the people - that is a shallow and frivolous approach. Of course there were villains, quite a few of them. But most of those who came to power had the intention of serving the "toiling masses" from which they themselves had come. That the system rendered their aspirations useless, reduced their efforts to nothing, and ultimately snuffed out their finer impulses - that is a separate question.
