I think Chaos Control should be changed. Don't make much sense. What will happen? Will the GM play? Will the PCs keep going? Fear and Hope at the same time are not really worth it.

Because the rule says "regardless of the outcome", it means whatever would happen in the roll still happens, just that 1 Hope and 1 Fear are also generated; so if the player rolls with Fear, the GM still gets to make a GM move.
Another way to understand the move, is that you're paying 3 Hope to give another player 1 Hope, and the GM 1 Fear. This is useful since many of the Heretic's features are affected by how much Fear the GM has.
