If you believe what the Bible says, and you are a christian, then you should strive to become more Christ Like. The Bible says to do so.
Is it possible to not sin?? Well... we do have the power to choose our own actions don't we?
and aside from the right and wrong issue, Jesus was a loving man, cared for the lower societies, he was meek, he was humble, he was forgiving, he was stern, and much more. Just read the Four Gospels to understand just what kind of person Jesus actually was.
