Yes, but Cap hasn't been poked, prodded and mutilated like Winter Soldier. Plus, Skull has a vendetta and resentment towards Steve since the true SS formula worked on him without fault. And I doubt WS has the true SS formula in him, so there's another reason why Skull wouldn't want Cap dead just yet.
