Yes, I would.
But the situation is that the GM accidentally did something they didn't mean to do and by fudging they're merely correcting to the situation to what they intended it to be in the first place. They might just as easily declare that orc berserkers 4 and 5 just have a sudden heart attack and die, but that would be far more jarring and negatively affect the narrative than just fudging the dice so that the berserkers miss a bit more than the dice would dictate.
Change the stakes and you don't have to fudge the dice: The berserkers knock the PCs out and take them to the Eye of Gruumsh as worthy sacrifices (especially that elf wizard). Then you don't need to ignore dice results. The story continues when the PCs awaken in the shaman's gruesome lair.
