Sorry all for the change in my post. I lost what I originally wanted to say in a browser crash. Sorry for the seeming flip flop of opinion.
I do think a person can only cheat once, but I also think that most people cheat. We aren't naturally monogamous creatures.
I'm sorry but I think that line of reasoning is utterly asinine. I've heard it way too many times before. If monogamy is so contrary to human nature, then WHY THE HELL DOES IT HURT SO BAD WHEN A RELATIONSHIP FAILS? Sorry for the shouting. But really, why is there so much pain when you have to end a relationship? Think about that for a minute... Thought about it? Good.
First of all, it has been scientifically proven that there is wiring inside the human brain that makes monogamy - for lack of a better way to put it - feel good. When things are done to short circuit this wiring, things go very wrong and a person will feel bad, awful, depressed, what name you. It has also been proven that children brought into this world need both a father and a mother in a stable relationship for their optimum development. IF the parental relationship goes wrong, was never "right" in the first place or is incomplete (single parenthood), then emotional, mental, social and intellectual development will be compromised. The result? The kids usually going "wrong", becoming delinquent. We've all seen and heard about it all around us. It goes all the way down the line.
Furthermore, it has been scientifically documented that there are species of birds and mammals that make only one pair-bond for life. "But we're not birds, but apes", you say? We were created (humor me please) with genetic aspects similar to that of many species. For example: because we have relatively bare pink skin, we have almost as much genetically in common with swine as we do with apes.
I'll admit that there is also some wiring inside the human brain that manifests itself in tendencies towards infidelity, the "instinctual spreading of genes" thing. There is one more piece to the puzzle. The human intellect. It gives us the unique ability to plan our actions with the future in mind. We can use it to decide between what is beneficial or detrimental to our self interest or the interests of others.
We thus come to the matter of choice. I think the real issue when it comes to cheating is whether or not a person is able to make good choices throughout life. Cheating is usually the result of a long string of bad choices a person makes throughout life, like who to be friends with, where to live, where to find employment, who to marry, when to marry, how to spend money, when to have children, where and how to raise them, etc. Sure, cheating is often a result of desperation, but what poor choices led the person there? Sometimes a person marries another because they've been deceived by the other about certain things. This is a truly unfortunate thing for the person being deceived and the person doing the deceiving deserves to rot in hell, so to speak. (I don't really believe in hell, just saying.) What is the vaccine against such tragedies? Learning to make better choices than one has made previously.
We finally get down to the moral character of a person. A person could make poor choices because of medical issues, emotional issues, mental illness, poor education or simply because they are morally defective. The ones who are truly lacking in character can sometimes change but not usually. These are the kinds of cheaters who are truly "once a cheater, always a cheater". These ones are the scum of the earth everyone should avoid.
