Mortally? I have no idea what mortally is. If you mean morally, it depends on your own views on what morality is. In certain cases you can make certain arguments. If your getting beaten or cheated on, then you could make the case. The window for moral divorce gets even slimmer though when kids are in the picture, and then much more thought needs to be brought into the equation. I would also like to clarify the difference between religiously right and morally right. Just because something is wrong on a religious level, does not mean it is wrong on a moral one.
Bad things could happen where it becomes necessary. People need to understand that. Everyone who thinks "no one should divorce" and "divorce is wrong" or "those divorced people are terrible," I recommend you read the book Hush, Don't Cry.
Because it's immoral to force people to stay married in an unhappy relationship,especially if it's abusive.
No, but it is *morally* right. It is immoral to force someone to remain in a relationship that they don't wish to be involved in.
Marriage should be left up to the two individuals, and the decision to divorce should also be left to those two individual. If one of the individuals is abusive, manipulative, cruel, or just a plain jerk, then divorce may seem like the best option.
Yes only when you have a good reason like if you are going through child abuse or something
