Suffering is just a sensation. Pain is a sensation no different from rubbing your fingers on some material like grass or carpet. The only reason people obsess over suffering as a catalyst for spiritual questions is because suffering precedes death and makes death more appealing than living and so raises questions about the afterlife. If I got kidnapped and tortured by the cartel or thrown into the fires of hell I would quickly become acclimated, the immediacy of pain would lesson and it would become apparent how hollow and illusory my sensations are. Same with pleasure or any other human experience.
