maybe if you ' re a deist . The christian god certainly deals with good and bad . He even goes out of his way to define them . <| sep |> As far as consent goes , I thought it was implied that both partners are honest , and I know that assault or attempted murder charges can be filed for intentional deception of a positive HIV condition . The problem is that your proposed situation is the result of one partner lying to the other . If you can think of a foolproof way to stop people lying the best of luck to you . Because someone has the potential to lie doesn ' t mean condoms should be required . Just because someone claims they can swim when they really can ' t is no reason to force everyone at the pool to wear arm floaties . And as far the testing goes , there ' s a reason why bimonthly testing is standard as it helps to catch diseases in cases like you mentioned . In the end though , it mostly just comes down to people in charge of their own safety and integrity .
