In Wings of Liberty this was done as a form of R&D with often irreversible choices presented throughout the game.

I suppose the difference is supposed to be that Kerrigan was under the influence of the evil space monsters, whereas Mengsk has freely chosen his path in life. While Wings of Liberty presented simplistic characters, often stereotypes, its story handled more subtle and nuanced topics: can you feel sympathy for an “evil” monster, the Zerg Queen Kerrigan, can you want to save that creature? The latter seems to scale back these themes to being just a simple idea: the dictator Mengsk is bad, he deserves to die.
