I think imprecatory prayers are allowed but it’s better to follow the biblical wording ( as in the psalms) to avoid it from turning into a curse itself.
Indeed. In the Monastic Diurnal, the Saturday Lauds festal canticle is Ecclus. 36:1-13 and follows the spirit of what I think OP intends
[1] Have mercy upon us, O God of all, and behold us, and shew us the light of thy mercies: [2] And send thy fear upon the nations, that have not sought after thee: that they may know that there is no God beside thee, and that they may shew forth thy wonders. [3] Lift up thy hand over the strange nations, that they may see thy power. [4] For as thou hast been sanctified in us in their sight, so thou shalt be magnified among them in our presence, [5] That they may know thee, as we also have known thee, that there is no God beside thee, O Lord.
[6] Renew thy signs, and work new miracles. [7] Glorify thy hand, and thy right arm. [8] Raise up indignation, and pour out wrath. [9] Take away the adversary, and crush the enemy. [10] Hasten the time, and remember the end, that they may declare thy wonderful works.
[11] Let him that escapeth be consumed by the rage of the fire: and let them perish that oppress thy people. [12] Crush the head of the princes of the enemies that say: There is no other beside us. [13] Gather together all the tribes of Jacob: that they may know that there is no God besides thee, and may declare thy great works: and thou shalt inherit them as from the beginning.
