For everyone that is divorced while their spouse is still alive, do they go to hell? ?

Many of them have already seen the worst that hell has to offer.  You can believe what you will.  It still remains a free world.  But there is an awful lot in the Bible and people tend to choose those parts that suit whatever they personally wish to believe.

Yes.

That is why God gave humankind  arsenic. 

The Bible is far from definitive: the early church removed a lot of the more spiritual tracts and it has been mistranslated and misunderstood ever since. Of course, there is still much wisdom contained in its leaves and a lot needs to be read at several different levels, not least John. 

Life really is nothing like as simple as simply being good or bad and going to Heaven or Hell. Many religions take stands against divorced, abortion, contraception, etc. not for spiritual reasons but to ensure maximum procreation. Obviously in times past life expectancy was much lower than it is now due largely to infant mortality statistics.

Best not to try to judge people......

For some, the marriage was hell.
