Granted, I don’t think a monk taking a Vow of Pacifism should be docked integrity, since e is not fighting. But monks who fight at all should take some integrity loss:

But I say unto you, That ye resist not evil: but whosoever shall smite thee on thy right cheek, turn to him the other also. (Matt 5:39)

The thing is, there’s no way to refuse to fight.

There is a way to refuse to fight - Vow of Pacifism. We could remove the integrity penalty for Monks who have taken a vow, and possibly add extra damage dealt (since they’re not fighting back) to balance it out and keep it from being too powerful.

In favor of Isolde’s fix, if she proposes it.

Then consider this killed.

  Then said Jesus unto him, Put up again thy sword into his place:
for all they that take the sword shall perish with the sword.
