There can be a number of reasons why no one interfered in this situation and tried to help the women. First, she was on fire so people were afraid that they do not get themselves in the same situation. The second reason maybe that people were afraid that if they tried to help the lady, the investigation agencies might ask questions from them and put them on suspect too.

The above are all excuses and the real reason is that people have become selfish these days and they rarely care for others. We are living in a materialized world where the humanity element is decreasing every day.
could it be possible they thought it wasn’t a real person or at least an alive one?
i refuse to believe that people have become so selfish that they will watch a woman erupt in flames literally it feels like a witch hunt almost and they all watch as the witch gets flamed i hope whoever did this can be taken to jail and serve time and people in it might be penalized too or traumatized for watching that unfold
