If someone's will is to harm and destroy you or other innocent bystanders your options are to flee, shield yourself or engage. If the method that you choose to engage them is to ask the divine to change the desires of their hearts, then I'd see no problem with this.
If another's will would do you harm then it's within your right to ask that their will be changed. The divine won't necessarily respect this request, but I wouldn't see that the request itself would be out of line...
Interestingly enough, I think this may have been what happened to me, so thanks to whomever willed me out of that pit that I was in
