Just for the record, not all Christians are claiming 1 or 2 are true, absolute, or whatever.
Also, not all Christians are claiming that is what the Bible states.
I would like to introduce you to Sheol:
https://en.wikipedia.org/wiki/Sheol
The place in the Hebrew bible both the
righteous, and
unrighteous, go.
So, in the Hebrew Bible, we have this perspective of God, Satan, and Hell, and it changes as time passes.
So we cannot claim the Bible says X about Hell. It is not simple and it is not black and white.
So in the Time of Christ, this really gets interesting. This is the beginning of the Second Temple Period, which
begins 70 CE. The gospels start to be written in 70 CE, and are written by Jews, in the context of their beliefs.
In 70 CE we have the destruction of the Jewish Commonwealth, destruction of Jewish social and legal systems, destruction of the Temple, the destruction of traditional Jewish schools of scholarship.
And what do you know, some guys starts writing the New Testament in this Time period. What a coincidence?
Specifically, Pharisees.
https://en.wikipedia.org/wiki/Pharisees
Pharisees were fans of Rabbinic Judaism.
https://en.wikipedia.org/wiki/Talmud#cite_note-136
which refers to a collection of Jewish writings called the Babylonian Talmud
Yep, in the New Testament, the time of Christ, the old testament was not the primary basis of Jewish belief.

Now, I am going to skip a whole bunch of context here, but basically say this.
If a person takes into context the Talmud understanding, who the writers were, where they lived, what time they lived, who they claimed to be. In all likelihood, in the proper context writer who wrote the book of Mark was not claiming hell was some eternal whatever.
He was most likely claiming people put themselves in the equivalent of Gehenna, a burning garbage dump, in this life.
Please, please, do not paint us Christians all with the same brush.
