Venganza knew there was no way to reach an agreement with the Terkollek Race, and the only way in which the people of the Daybreak Universe could use this place as a safe haven during the next war would be by eliminating them.
Genocide was not something that Venganza would take lightly, and he understood the burden of such actions, but there was no hesitation in his heart that this was the right path.
Terkolleks only lived for conquest and assimilation, so even if the Revenge Thearch did not need this universe, he would still erase them since if they managed to expand beyond their Cosmic Wall, they would become a great danger to the Emptiness.
It would not be easy since this was a powerful super universe, and even with the Lamp of Eternal Justice that the Samsara Thearch gave him, Vengazan could only suppress the powers of the Universe Will and not fully paralyze it.
