It is fairly assumed that dark Berserker was already down to his last life from fighting dark Saber, or Godhand wasn't even working properly after becoming dark.
It can also be assumed that a giant temple stonesword to the crotch is worth 9 deaths.
Godhand increases resistance to the same type of attack/death each time Berserker is hit by it. No form of spammy works on him, other than gates of Babylon, which is a few thousand different noble phatasms of A rank.
The writing is fine if you were actually, you know, reading?
