Many Russian people have said on this forum that Gorbachev was a traitor.
It seems to be a common opinion.
What is it exactly that you don't like, that he did? The Glasnost idea? The perestroika idea? Allowing the USSR to disintegrate, or what?
What should he have done differently? Would you have preferred if he had never been president of the USSR at all?

What do people in other ex USSR countries think about him, for example Ukraine and Belarus?
