I am not religious but many things in religion come from centuries of wisdom. There is one vow which is a social necessity and that is something like... let those that have been put together, let no man put down. We should not interfere in other peoples relationships because we may never know the extended damage that can be caused to the couple, family, children, pets, property, finaces and extended family which can stretch for decades.

Both parties should be held accountable according to how it goes down. It also depends on how and why this was done. If your dating, then yu can't do much about it except let the person go. In marriage, you have to look at yourself, your spouse and the one caught in the middle. What led to the infidelity? 9/10x in marriage, it's because either the wife or husband keeps sexually neglect the other and when the opportunity arrives, the one who is neglected gets tempted and often do it if they no longer can control that temptation. If there is a good indicate amount of sex in the marriage, then this has to do with the kind of person the cheating spouse was in the beginning. At this point, this is not entirely the suffering spouse's fault. UNLESS that spouse knew the kind of person or habits their spouse was before they got married or dated in the first place. At the same time, it also depends if this was sexual infidelity or plotting to cheat. Sometimes it's not always the other woman if she never knew he was married. You have guys or people who don't wear their wedding bands and hide them for the sake of cheating. So it's best to get to the bottom of how it started before blaming other people for something your spouse chose to do.
