Yes and no. I haven't read Tolstoy yet, and it's on my bucket list to do so. Ideally I'd like to go into that without any major spoilers.
But at the same time, if a book has stood the test of time of 120-years... the spoiler probably would only very slightly diminish my enjoyment of it. For example, even knowing the plot of the Sherlock Holmes stories and William Poe's mystery poems, I still get enjoyment from re-reading them, in a way that I don't from Dan Brown, for example.
