I wouldn't say there should be no consequence for using this power to bully people around, just that whether using the ability costs you Conflict should be more about player intent, and that what pips the player decides to use from their Force Dice are enough to handle it mechanically.
Alternately, we could take a page from the example of Force Powers, and offer a "Light Side" analog in the same tree. Where the 2 ranks of Prey on the Weak are now, create a new talent that more accurately reflects a more peaceful, less "evil" side of the spec's abilities.
Unwavering Will
Take an Unwavering Will action; Make an opposed Discipline check against one target within medium range, adding <Force Die> equal to Force Rating. If target suffers strain from <threat> this round, it suffers additional strain equal to <success> on this check at end of round. Spend <Force Point> to affect additional targets.
Improved Unwavering Will
When performing Unwavering Will, may spend <2 Advantage> to extend duration, or <Triumph> to recover strain equal to Willpower.
Supreme Unwavering Will
When an affected target becomes incapacitated this round, may spend 1 Destiny Point to revive them as an ally for this encounter. (Rival or less)
Essentially, it's less terrifying the enemy than showing you won't back down, and eventually being able to make them realize that "the Force is with you", and they're on the wrong side. I see a revised talent tree with Terrify and its associated talents on the left, and this one on the right, along with talents that focus more on steely determination and physical endurance than fear, and more on wearing opponents out than forcing them to flee. This talent's side of the tree wouldn't be as immediately powerful, but does have a unique effect and reflects what a Light Side-aligned person would do with it. It also allows for player choice that ties into the internal conflict of how to use these abilities. Quick and easy, but a little evil? go left. Slow payoff, but without the conflict? Go right. I'd imagine there would be nothing stopping you from doing both aside from substantial XP investment, but that too is a difficult choice.
If no reversion is desired to Terrify, then what do you think about offering an alternative in the same tree?
