Unease swam in the pit of Regulus's stomach, making him nauseous, but he couldn't come up with a reason to discourage that plan of action. Of course he'd seen where this was going, but he'd thought that Snape wouldn't guide Mulciber to the logical conclusion. As far as Regulus knew, Snape had nothing against Granger, at least not enough to wish her death. Regulus wanted her out of the picture, but not like that. Just imagining what the Dark Lord would do to her was enough to make his insides contract. However, he wasn't nearly fanatic enough to feel safe in expressing opinions like that. Any dissent voiced now would be seen as a betrayal to their Lord.
