True it would also be bad to be on the other extreme, with everyone playing a cutthroat game for world domination, rendering alliances and friends useless (unless you like it that way ). But it's no less maddening than having all the AI be docile. A good compromise would be to have each AI have a "favored" way of winning. So while an agressive civ might bully everyone and try to expand through conquest to go for the military win, a scientific civ would build alot of defense and research their way to a spaceship win. Meanwhile, a cultural civ would put alot of cash into their culture slider and flip lots of cities while going for the cultural win, daring you to try and stop them without going to war. The bottom line is, it would spice the gameplay up alot if the AI actually had some motive, some goal to reach by the endgame. They don't necessarily have to be cutthroat killers that always take down the top dog (for instance, a pacifist AI's goal might be to stop everyone from fighting and win through diplomacy!). I'm just disappointed that there are SO many great games that could result from goal-oriented AI behavior... it just seems like a lost opportunity that would give the SP game alot more personality.
