The Eternals snuck inside the Progenitor's head and beat the crap out of his spirit/soul/ghost/whatever... I don't think he can be any more pissed at the Eternals than he already is, no matter what they do...
Eternals ARE overpowered; each one of them has the combined powers of a whole team of Alpha mutants... but Uranus is in a league of his own... he has been implied to be a serious threat even to Thanos, and Thanos has curbstomped whole teams of heroes that had Hulk, Thor, Iron Man, the Thing, Captain Marvel, Silver Surfer... etc., in them, has fought Odin (the old Allfather Odin, not the latest Chump Odin) as an equal for several minutes, and has slowed down Galactus himself...
Why would she be angry? They couldn't drag her unless she allowed them... she could win any debate or any dialectic battle if she just chose to...
