It's probably worthwhile to distinguish between functional and final judgments. It is impossible to go through life without making judgments. A light turns yellow. Can we make it or need to stop? One has exercised judgment.
1 Corinthians 2 says as spiritual people we are to judge all things. We can shirk this responsibility or not. But making functional judgments does not mean we should or are even qualified to make final judgments.
In the example above, if a person neglects the care of family, they are in general transgressing the law. If this is an ongoing practice devoid of repentance, especially if the person has been shown the offense, it constitutes rebellion.
It is reasonable to assume that the individual has yet to pass from death to life.
There is, however, a grave danger in saying this with certainty. Our observations are limited regardless of how well they are informed. We lack the ability to discern the heart. Thus, all judgment for us means functional, not final.
