It's not
I'm not talking about virtue- just that sometimes it can be best to end a relationship abruptly rather than drag things out and ultimately cause a lot more pain, both to yourself and the other party.

not really sure it's your place
to end someone else's relationship in such a manner.

but I appreciate the compassionate sentiment.

As the single party
The only relationship that you're ending is the one between you and the attached person. If they're going to stay attached and it's going to get emotionally messy then it's better to walk away. If their other relationship ends then that's not your problem- they should not have got involved in the first place and it would be their looking to have an affair that ended it- after all if it hadn't been you it would more than likely have been someone else.
