Friend, if I'd known you were gonna ask here, too, I'd have saved all of my typy-typy time and put it in a comment.
So anyway, I think you are conflating morals with values. What is confusing to (some of) us is that a WS will say they knew it was wrong, but the key question to ask is by whom were those actions/choices defined as right or wrong? The Bible or other religious text? Society? Certainly not him or herself, right?
In my mind, morals are rules that are defined by "others". By an external source, whether it's a commandment, or a religious leader, or even a law. There is usually a consequence that is more or less known if one goes against the rule - jail or hell or divorce or something else.
So when these external rules bump up against a situation where the person does not internally VALUE the essence of what the rule or moral is promoting or forbidding, you get someone who is at risk of going against the rule and using rationalization, compartmentalization, justification, etc., to do so.
Stealing, for example, is wrong. We all can probably agree to it. But philosophically, I can say that I would steal if I had no money and no other way to provide food for my kid except to steal (let's put aside for the moment the argument that there are social agencies in place to prevent the need to do that). And that's because I value feeding my kid more than I'd value *not stealing*.
So a wayward who has ("serendipitously", or who pursues) the opportunity to cheat...well, they don't VALUE fidelity. They know it's wrong - there are rules that tell them so - but they value something else (ego kibbles? more sex? a great body? just the fact that the opportunity is in front of them? etc.) more than they value being faithful. They can tell themselves whatever, but the fact is, while someone can break a rule or behave immorally, I have a very hard time believing that one can violate something that is internally hardwired as a core value.
That's why I have been saying that cheating is about having an external locus of control. A different way of saying that is the aphorism, "There’s something wrong with your character if opportunity controls your loyalty." Because a person of "good" character - a person of integrity - isn't going to go against a core value: "Integrity has no need of rules," as Mr. Camus pointed out.
Morals are rules, and rules...well, they say rules are made to be broken. But a mature and self-aware person isn't going to violate a deeply-held core value.
So I wouldn't say they didn't have morals*, but I would say that they were able to choose immoral behavior because they did not have the values in place to prevent from making those choices.
You can say "I value (or do not value) xyz..." but you can't say "I moral (or do not moral) xyz..." Morals are external, and until they are internalized and become values, they're still negotiable in the mind of those who can be swayed by the right (well, wrong) opportunity.
