I think you're being a bit too emotional here, and your opinion may be a bit couloured by the current regime.
What I remember (and have also read) about the happenings around the late '80s & early '90s, makes me think that Gorbatchev tried to reform Soviet Union, but he had too much opposiotion from the old regime, and then it all got out of hand - too much, too quickly (but too late). If he had had the support of others vying for power in SU at that time and succeeded, the result may have been similar to what has happened in China during last 15 years.
What you have now in Russia isn't what M. G. wanted to happen, but it its still much better than the reign of terror that invaded Hungary 1956 & Czechoslovakia 1968.
