Are you allowed to daven for someone else to get punished? In other words, if a real Jewish rasha in every sense of the word does bad to you for no good reason and you feel incredibly hurt, can you daven for them to get punished? Assume that the person continually wrongs others.
It is true that Hashem will punish them anyway, but if davening makes you feel better, is it considered inappropriate or even wrong? And, if so, are there consequences to doing so? (Such as other tefillos becoming nullified because you davened for someone to get harmed?)
