Present situation - J, Anandi and Mangala all r wrong in taking Nimboli with them. But at least Mangala and J tried another option before. It's not social work - it's trying to save Ganga and perhaps he has planned to save everyone but it's still risky. What anandi did was criminal negligence without even thinking about the child - there was simply no need to watch that bullets tamasha - any stray bullet could have injured the child.
Criminal negligence is not equivalent to premeditated criminal activity.
