Yeah. At this point my characters might just hand the box back to 'em. We're not given much reason to keep it (except Shadowheart objecting, but she's not even around in most of my playthroughs).
I get the feeling that even if you give it back, you'll end up gaining it back anyway. It pretty much force Shadowheart to commit suicide so you pick it up from her corpse if you do no recruit her (you need to win DCs to not kill her).
