Unfortunately I am still unable to find any stories that tells what happens to the Hamas members after their surrender. I’m unsure if they get treated well or are sent to the same facilities in which there are reports of human rights violations amounting to psykological and physical torture.

I did find some examples of successful surenders, but nothing where hostages were explicitly mentioned to have sweetened the deal of surrender.
I do believe you may be right but I have been unable to verify it myself.

Are there any examples of it being used successfully and the aftermath of it? This is a genuine question stemming from my own ignorance on the subject. I would really like for that to be a good way of handeling situations where hostages are released, but I could easily understand why a member of Hamas might have reservations if they do not have reason to trust the system.
If there is good reason to trust it I will agree that that would have been a viable and good way out and should have been used.

To me it sounded like they were specifically pushing against a claim that Hamas offered to free everyone. They pointed out that they only said civilians and as not all hostages would be considered civilians not all hostages would have been freed as another commenter claimed.

I still see it as them pushing back against an “Hamas was good actually” sentiment, arguing that Hamas was not as good as implied due to a careful reading of the statement and an assessment of the hostages and whether all were civilian or would be considered civilian by Hamas.

There is a greater context, but the thread in which this was written the context was a push back against claims portraying Hamas favorably.

Do you really believe that any member of hamas would be safe just because they let some hostages go? How would that work? Should they surrender themselves to the IDF while delivering the hostages, just notify them of where they are so they won’t be bombed or how would that all work?

How were they doing that? To me it seemed like their point was a distinction between all hostages and civilian ones being released. I don’t know if they are correct, but I cannot see how it in any way dehumanizes anyone.
