Uh... i get that Ogryn a huge and retartedly strong (pun intended) but he was not an ideal ally in that situation for a bunch of reasons, namely he was unarmored and already wounded. second i dont recall you sticking around to ensure that he had understood the plan, giving Azazel a window to react before the ogryn was uppon him... a .50 cal bullet to the unarmored leg (regardless of detonation) would realistically stop almost anyone, marines and ogryn included. 

lastly, the minion Ga'duk hit could very well be out of the fight, at least temporarily as he wakes up from the concussion or disentagles himself from the collapsed cabinets and shelves.
