hello, some mention that suffering is relative while physical pain is not and that this would explain various reactions to a "similar" event, but you have proposed in your question an extremely complicated scenario (a traumatic hell / extreme inhuman torture ) that I consider that I have not transited so I cannot answer you about any experience of this type and even if I did, it would be different from yours and it would not work either because we are different
Regarding your question, it may be because they went through a period of suffering and over time they realized that thanks to that they now live in a better way, the experience has added up and they have finished the process they were going through, but also the opposite has to be considered, what you mention here, how traumatizing and inhuman and I don't know, but I have heard cases and the solution was love (quite a cliché), love in the sense of unconditional support from those close to them thanks to them they were able to finish or advance in that process
basically my answer is: I have no idea, that they have not experienced something this complicated and even living it would be different because nobody knows how someone would react to that
If you look at it from another point of view, the system uses these types of sentences, because this is how the problem is taken to the person who suffers instead of improving the system in which we live, shit, and you can see this in the systems of self-improvement, those who write their systems and give conferences earn money with it, the pharmaceutical system sells you pills to "help" you, therapists charge you for their services to "help" you and the list goes on, for example the other day I was checking Youtube and a video of that style appeared, I saw it and I was surprised, the person was trying to increase the weight that people carry, that you should do more, that you are doing this wrong, that if you are X old, there is no turning back and another video where the connotation of the words changed, instead of saying responsible they said being aware, and instead of saying exploit it they said explore it, creating confusion and that is the issue, because if you see it they are motivators that companies hire
maybe the real answer for some of those people is money
greetings
