No need to lynch anyone: after all, Marx didn't feel that capitalists were evil, he felt that they were just doing what the prevailing economic system forced them to do: to squeeze profit out of workers to avoid being outcompeted and driven to bankruptcy by the other capitalists. But (most of them) are not actively evil and don't need to be punished. So you could just let them live but take their stuff, and there does exist wide support for the notion of forcibly taking at least some of people's stuff (via taxation).
Marx didn't think that you can simply get a democratic majority and tax rich peoples wealth away via taxation. He considered that no viable political strategy but advocated revolution. You ignore the political actions that Marx advocated. In dialectics a thesis needs a contrasting antithesis to allow for synthesis.
Stalin also didn't kill people because they were evil. That's besides the point. The action that resulted in dead people were justified because they move history along.
