Hmm I don't know, the two ter'angreal Wise-ones use seem to be altruistic to me, as does every ter'angreal so far.
The glass columns ter'angreal seems to rely on people to do themselves damage judging by what Rand saw of the Shaido potential clan-chief.
And the rings ter'angreal admittedly has less evidence either way, but the fact no other ter'angreal we have seen has built-in dark-detectors to me says that it doesn't have any special measures either.]
And naturally if she became a DF after becoming a wise-one then the argument is mute about these ter'angreal.
