Not really. Just because you can't die. Doesn't mean you can't be knock around. Wondy was getting stomped by Doomsday, that was pretty clear. She only got lucky with Ares because he is a god and as you may know, only gods can kill gods.
Really, she lacks the physical capacity to defeat Doomsday on her own. But hey, don't get mad at me for it, not my fault script writers for Warner and the DCEU don't know how to make everything coherent. But what is established in the movies, is established in the movies. You can't deny what is obvious.
As a matter of fact. Maybe, with the right amount of time (since Doomsday was getting stronger by every second) and if given the Kryptonite Spear to Diana, maybe the sacrifice could have been avoided. Unlike Batman, she actually has the strength to push the spear inside Doomsday. Maybe make Superman distract him, make Batman fire the last round of K. Grenades, take impulse, jump and kill the thing.
