Lenin left Stalin in his place.
Who else did he feel could suceed him? He handpicked Stalin, appointed him party secretary, among other things. Claim, as you mujst that this was only an attempt to get him outta the way, but... party secretary? The party was not hijjacked my freind.
Interestingly enough (as I have said in the past) When asked which man was harsher Moltov recalled Lenin reprimanding Stalin for being too soft. Lenin died after giving Stalin instructions to begin purges, I will admit that he did not instruct anything like Stalin did, but he did ask for purges.
Lenin was not a saint. He was a coldblooded son of a b*tch. He left Stalin his sucessor, he was no hero, remember that his very entrance into his nation was betrayal of his motherland to Germany. Is this your hero? Idealism? bah! Fanatical murderer.
Karl Marx, if you want religious leaders, caused more deaths than anyone else.
