Pretty sure Yon Rogg has nowhere near the same powers as Vers.

Either way, its a good trope to have the villain be the opposite of the hero simply because the scenario of opposing ideals in similar/same individuals is interesting on paper. Parallel characters that took different paths and whatnot. When done right its very appealing, TChalla/Killmonger being one example. When done wrong is boring as hell, like AntMan/Yellowjacket. The MCU however has exploited this way too much to the point of exhaustion.
