So orcs are targeted viruses now. To me, they would function as kind of a violent MacGuffin--they exist solely to slow down the PCs while they go after the actual cause, the root of the disease. Which in your case, is Gruumsh.Put this another way. Let's assume some alien civilization out there was at war. They create "the perfect soldier" by messing with their DNA and creating clones. They've altered the brain structure and chemistry so that they have no empathy, will not hesitate to follow orders and kill. But something goes wrong, their commanders die before they can shut down their soldiers and so they are following their last orders to the best of their abilities - kill everyone who is not part of their command structure or a fellow soldier. In order to continue the never-ending war, they figure out how to make more soldiers. There's no biological basis for them to have any moral qualms about killing someone outside of their order, in fact they are instinctually driven to kill every "other" that could pose a possible threat.
Seems like a waste of an orc to me, though.
