Jesus said "Judge not, that ye be not judged. For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be measured to you again. And why beholdest thou the mote that is in thy brother's eye, but considerest not the beam that is in thine own eye?"

He was not saying "thou shalt have no moral compass". In fact, he was commanding us to "be holy as God is holy" and, having removed the beam from our own eye, to help our brother remove the splinter from his.
