yes, a game about corruption, but corruption for what purpose? I think it's wrong to call the game a game about corruption - it's a game about an insurgency that uses corruption for a good cause. it is quite different than when they corrupt purely for the sake of satisfying the base needs of one pervert (like MC in VN "Cure My Addiction"). in this game, corruption is a useful tool to achieve something big.
it's like a knife - the chef will prepare a great salad with a knife. a murderer with a knife will kill a possibly kind person. although a knife is just a knife. it all depends on the person and their goals.
