Would you lie to/use someone if it was mutually beneficial?

@Emele thinking you and the person, mostly.

@NorthernRoses I can't really imagine a scenario where lying would achieve that, maybe withholding information that benefits you. That would sort of be using the person. As they would be acting without full knowledge. I would be most likely to do anything approaching deceitful if it only affected myself. At work I have told 'white lies' or half-truths to help myself out...
