Since when is expressing a fear a judgement?
Please re-read to note the phrase, "may possibly involve."
If I were to say, "I fear Jones may be about to start sodomizing his nephew," in public and without evidence, I am judging by insinuation. This is wrong in proportion to the wrongness of the act being discussed. If the act would be a trivial fault, the insinuation is a trivial fault. If the act would be a venial sin, the insinuation is a venial sin. If the act would be a mortal sin, the insinuation is a mortal sin --- assuming the usual conditions (adequate knowledge and intention.)
I am just reminding you. I assume we all know this.
