The Reasoning Behind Mass Suicide and The Types of People Who Get Involved

So... Why do people commit mass suicide together?

When groups like Heaven's Gate Cult commit mass suicide they do not see it as suicide. To us, we see it as bizarre but, they saw it as moving on to another dimension of existence. Much as that of Hindu or Buddhist would, in the sense of a reincarnation or migration to another realm of being.
So now as for the next big question... Just what kind of people are joining these groups?
Most often, it is people who are searching, and are discontented. They are idealists. They often times are very bright and creative. They are the people who go on search for a more exciting religion because they become bored with the traditional types. They seek adventure and want to stray from the norm. The reason for their search and adventure is because they are looking for absolute answers.
In these cults you have two different types of people: First you have the vulnerable ones who are searching and frustrated. Then you have those who are very adventurous and tend to have creative answers for nearly everything. However, they tend to be isolated from society and they become known as the misfits. The cults create a sort of fake family seeing as how all these members lived in a house together, but they rarely talked, most of their time was spent in front of their computer screens.
