Why do you think Helaena told Aemond exactly where he was going to die?
Helaena didn't seem to have a negative attitude towards Aemond from the very beginning. But after he grabbed her by the hand and tried to drag her to the war (right in her bathrobe and slippers lol), she got mad at him. She refused to help him and said she saw him burn Aegon. And that he will not win, he will die. But there is an interesting detail. She told him exactly where he was going to die. She didn't have to specify it, but she named a specific place. Maybe she decided to give him the opportunity to try to change his fate? After all, theoretically, if he doesn't approach Gods Eye, he won't die there. After all, he's her brother, and even if she condemns his actions and she doesn't like the path he's chosen, she might have some affection for him, and she could try to give him a chance.
