While Stalin certainly bis one of the greatest mass murderers in history, it should be noted that concentration camps, summary executions, mass reprisals etc. etc. where pioneered by Lenin who did not even shy away from calling them such. Whether Stalin offed him, or complications of syphilis were sufficient, had he lived longer it is unlikely that the death toll would have been significantly different.
