It's not a flaw... how the AIs play faction leaders, and how you choose to play them, are not the same thing. Let's face it, most 4X players relish torturing their vanquished enemies! And if you really didn't want to torture anyone, you could (1) make them swear a pact to serve you, which implies you didn't do certain nasty things to their faction to begin with, or (2) let someone else kill them off.
