Why didn't the other 9 lepers show thanks?

The other nine lepers didn't show thanks likely due to a combination of shock, urgency, and the overwhelming nature of their healing. After experiencing such a profound change in their condition, they may have rushed to rejoin their communities or address other pressing needs. Additionally, their lack of gratitude could reflect a common human tendency to take good fortune for granted when faced with life-altering circumstances. Ultimately, their response highlights the importance of mindfulness and appreciation in the face of transformative experiences.
