Why was adultery SO bad...?

I totally agree with you that getting stoned to death because of adultery is insane. The truth of the matter is that adultery is a of trust for the one you love. I think people get over this matter because alot of people who actually cheat don't give a darn about the one they are with. But sometimes, things happen in the relationship that make people go outside the marriage for comfort. Well, to wrap things up, adultery is bad and it takes a strong person to move on from the situation.
