When someone threatens suicide it isn't the observer's place to make a subjective judgment about whether or not the person is serious or a drama queen. You treat it seriously. That way if it is real the person gets help, and if it is fake the person learns a lesson about reality and consequences in a spirit of genuine concern.
A great deal of suffering and inhumane treatment results from these invasive judgments about what is going on inside another person. This is worsened when these assumptions lead to a desire to punish, especially group punishment and shaming. Why would the act of being a drama queen require the punishment of egging the person on? How would a flippant observer know enough about psychology to have a slight clue about what such a person would need for rehabilitation. The observers behaved inhumanely regardless of their motives.
