Judgment people focus on spiritual transformation rather than balancing worldly relationships like Justice types do.
In my favorite deck, there’s an angel with a trumpet that calls souls to rise. People with Judgment energy do something similar; they push others toward their spiritual path. The guy your querent is asking about seems to embody this.
He went through his own transformation and now feels compelled to help others align with their spiritual purpose. Sometimes people aren’t ready for that kind of push, though.
