If by communism, you're referring to the ideas espoused in Marx's Das Kapital and the Manifesto, then you probably might want to make an effort to actually read these works. They are anything but evil, and unless you subscribe to the Cult of Ayn Rand, you'd probably find them rather interesting.
That being said if you're (more likely scenario here) referring to the garbage Stalin/Mao-ist regimes that haunted Eastern Europe and other parts of the world for the late 20th century, then yes, that is pretty evil.
Now to answer your question; I personally can see very little differences between the Stalinist Nations, and the Facsist Regimes of Hitler, Mussolini, Batista, Franco, or Pinochet. All of them used fear and brutal suppression of political opponents and free press to stay in power. They all had state-controlled markets, they all had a personality cult based around their leader(s), and they all massacred countless innocents. The only major difference that I can see is that one group liked to do business with American corporations, and rub the feet of our leaders so they would turn a blind eye, while the other did not.
