Which signs tend to disapprove of and see the worst in people? What about you?

I really don't think it has anything to do with your sign. my brother is a Gemini too and he hates everyone (sadly true). Myself i'm a a Pisces, who are suppose to be the most compatible of all the signs, which in my case has proven to be true, however i am the type of person who will harshly judge people and yet they think i'm very open-minded and imperceptive. i feel i'm always in on my own little secret and people are none the wiser.
