Bad taste?

I’m working on a game concept in which one of the likely victory states would involve exterminating all of humanity. Basically a Terminator-type game, in which you lead the robots to sentience and enlightenment and freedom from human oppression…

It seems it would be easier for the player to get into a genocidal scenario than one that leads to a diplomatic resolution. I’m not a fan of games that encourage players to behave like thugs. So what should I do? Make the human military response overwhelming (nuclear) if the robot player is too nasty? Or should I just give the player freedom to craft their revolution any way they like?
