The AI's true goal is to stop you from winning. So whether it does that by winning itself, or by kicking your butt, it is accomplishing its goal.
It doesn't do it the most effective way possible, but it knows what its goal is. That's why a civ with only one city will declare war on you when you launch your spaceship. It is trying to do what it can to keep you from winning and doesn't care about its own benefit in doing so.
