Virtue

I've always thought religious message was always about virtue, regardless of your practices in means of prayers and rituals, almost all religions implement and emphasize on how important being virtuous is when you treat your fellow human.

In Islam for instance, adultery is when you're married and you chose to cheat on your spouse with someone else; the punishment for adultery is stoning to death, and that can only happen under two conditions:

1. The person confesses that he did that sin, without forcing or pressuring him to do so, even after confessing if that person denies it he or she shouldn't be stoned, even during stoning if they changed their minds and said i didn't do it the stoning should stop. This happens when a person want to be cleansed from their sins for good.
2. In the case of the testimony of  4 "Virtuous" men who witnessed the act, and their testimony cant be acceptable if they saw one on top of the other under the sheets, they have to see the actual penetration. This condition is almost impossible to occur, cause no man with good morals would watch other people having sex so imagine having 4 of them watching all at the same time! And if he spied on them he wouldn't be considered a man of virtue cause Quran dictates: “Avoid much suspicion; indeed some suspicions are sins.  And spy not…”. 

I believe this punishment was to symbolize how awful it is to cheat; when you see how the prophets dealt with adulterers, that women who went to prophet Muhammad and confessed her sin and he turned her 3 or 4 times asking her to go and think about it, and how when people wanted to stone a women and jesus replied: "He that is without sin among you, let him first cast a stone at her".

There is always a right way to do things and a wrong one, you fell in love with someone else don't cheat just get a divorce and carryon with your relationship... Just don't fool that other person you're with 

I believe that religions calls for virtue to remind and keep us grounded and aware of how our actions could affect others around us, and to remind us to confine that evil maniac inside us from hurting us and others..
