I heard from a very respectable rebetzen (Not some fancy shmantzy silly principle in an e”y sem…) a really brilliant woman, who said that when you cry/shed tears from something that someone did to you, it is very bad because it can cause a kitrug or something like that on that person. So if you find yourself very hurt, you can actually take those same tears and turn it into a tefilla and that tefilla is considered a tefilla that was said with tears which is very powerful! (even though the tears were not originally brought out from tefilla!)
So instead of warning people not to hurt others, we just reverse the roles of victims and perpetrators.
