My birth chart says im evil?

I am a western astrologer, and truly have a different take on things. Being born Dec. 18th would probably have your Sagittarius at around 26 degrees (truly depends where you are born, and time), but if that is so, you should still be in the orb of the galactic centre. This is a very powerful point, and many very successful people in Sag have this. The most negative thing I see with this is the ability to lie. But if you stay within you truth, this is a wow factor. Maybe look at the western version, and please learn a little about astrology, or see a good knowledgeable astrologer. Because, this in my opinion can be such a great chart to look at.
