Depends what you have to do to 'bribe' them... And it might be continuously as they might be willful and uncooperative. Unfortunately you might have to come up with whole game mechanics of that sort  which we havent seen before in the Bioshock games.

Frail in some way not made clear as they did that self-repair thing (had to be invulnurable to our fire in the game to please the censors), but they also were the target of Splicers --- did they want to 'harvest them'  like we could, or was it more kidnapping to get them to work for the perp? They supposedly generate ADAM without even having to process 'angels' (just alot less potentially than recycling from the corpses) and keeping them stashed away to make ADAM might have been a goal.
