None. No sign of the Zodiac is evil. Individuals are evil, not entire groups related by their astrological sign. The thing to remember here is that astrological signs are just a vague guideline. They're simply non-specific generalizations to use as a way of learning about people in general, and NOT a good way to judge character or personalities of individuals. Do you think every Capricorn man or every Sagittarius woman is exactly the same as all the others? Of course not. Our character and personality is primarily based on our DNA, our experiences growing up, how we were raised, what culture we were raised in, and a host of other elements too numerous to mention. Astrology plays an EXTREMELY tiny portion of who a person is at birth, and it becomes even TINIER as a person grows up. Taking that into consideration, you can see why the question itself isn't a sensible one.
