The question about Lenin is too complex. Very complex. People, who knows history well, discuss it even for now.
I think, you willn't get the correct answer on this forum.
Let me give you two advices to get the truth by yourself.

At first, you must specify your question. I think, you mean "good or bad" characteristic not for Lenin's person himself, but for the result of his actions for russian history, yea?
At the second, you MUST learn about conditions and state of Russia country at this time. Only after this you may think about his actions and results.

But, what isn't discussable - it that Lenin was greatest historical actor in the world history of XX-XXI centuries. "Greatest" didn't mean "good" or "bad", I mean that most of the further history (especially Cold War) was consequences of Russian revolution in 1917.
