Not everyone knows how to get help. If they had examples of others helping and seeking help for themselves succesfully then you can hold them accountable for not trying.
Regardless what the OP had in mind, who seems to have a rigid and unrealisitic view of cheating, just as unhealthy as the opposite view he described of people actively looking to cheat, if you want to leave someone just over cheating you will end up alone.
Sometimes people who chronically cheat were given this cheater example to follow and do not know better. Some say it takes two to tango but it really takes a lot more beginning with a spouse who does not give what the other spouse needs that they go cheat.
Lack of communication between two spouses means two people are already involved before cheating has begun. Add in a cheater now we have three involved and for all those who gave examples to these two spouses of not communicating, not seeking help with their issues, and even examples of cheating then we have plenty of people involved in one act of cheating.
Victims of betrayal who just call it quits also are at fault. Did they work on the relationship before or after? Many claim they did but in the end they blame the cheater and refuse to take any responsibility for their part.
The worst is that many of these victims of betrayal are damaged and therefore go off to give others bad advice of leaving after cheating so that others will end up miserable just like them. It is on some level just because they didn't know how to make their relationship work they want to see others fail too. How selfish.
Saying one spouse cheats over and over is the reason the relationship failed is also not accurate. If one partner was already cheating the relationship had failed way before that and cheating is just the symptom not the cause.
Of course there will be exceptions.
