In terraria, one of the most useful NPCs, The Nurse, is depicted in various works of official art wearing a white hat with the Red Cross on it. And although it is pixelated, and thus you cannot tell for sure, her hat in her in-game sprite might also have a red cross on it. As the CEO of Re-Logic, Terraria is your game & copyright, meaning anything that is considered official and/or in the game itself either had to get the greenlight from you, was added by you, or has since been removed/retconned, meaning you had a hand in this.
According to the GENEVA CONVENTION, depicting the emblem of the Red Cross on a white ground should NOT be done in either times of peace or war, except to protect or to indicate the medical formations and the establishments and the personnel and material protected by the convention.
Which means you, my good sir, are a war criminal.
Keep this in it's funny as hell
