In most cases yes, but in this case Lady Ven willingly took off the crest of Asylon as she was on a religious quest. Obviously it isn't ideal but a rogue is not always in that state because of criminal activity. Yes, this means she was no longer under protection of a realm but some characters might still have certain humanitarian or religious standards that fall outside of realm laws or lead to various interpretations on the justness or unjustness in how said laws are applied.
You can keep arguing this all day but it is pretty pointless. My character doesn't have to recognize the laws of D'Hara as legitimate, that is just the way it is. Saying that we cannot interpret the actions of D'Hara as unjust because it was lawful by D'Haran standards is a silly retort.
