There are many reasons why people commit suicide. People can decide to commit suicide themselves or be pushed to do it. Most of the factors, in reality can be explained by the Cost/benefit theory of Economics of Human Behaviour which says that people will do anything until Marginal costs will exceed Marginal benefits.
RELIGIOUS FACTOR - One of the most powerful social factors determining a level of suicides is the religion. Since according to Cost/benefit theory people try to minimize their costs while maximizing benefits and will only do something if Marginal benefits exceed Marginal costs. We can assume that if religious leaders would promise better life and god’s forgiveness of all sins people committed, some people under psychological stress would believe them and commit suicide since for the expected benefits would exceed expected costs. This is widely practiced in Islam. According to Islam to die for Allah is the greatest thing a living Muslim can do.
In Judaism on the other hand, value of life is emphasized, and consequently for the sake of preservation of life the devout Jews are allowed to break all religious laws, except for refusal of the god, murder and sexual relationship between relatives. The benefits of life are emphasized in Judaism and for Jews costs of suicide are large than benefits since belief in afterlife is not practiced.
In Christian countries it is a shame to attempt to destroy yourself according to the words of Bible. People who attempted suicide faced refusal of society to accept them and were buried on the edges of cemeteries or by the roads when died. Thus social and religious costs of committing suicide in those countries is very high and are greater than benefits of facing God in Heaven. This is one of the main reasons of the lowest level of suicides now in Italy, Spain and number of the Latin American countries - the huge influence of Catholicism in these countries. It is established by the modern researchers, that as a whole in countries, where the influence of religion is weaker and religious norms connected in particular with suicide are more humanely , the percentage of suicide attempts is higher. Because in countries with high religious influence God’s punishment for killing yourself is much higher and people are afraid to “sin” by even thinking about suicide.
In World History there were a lot of people who had the gift of persuasion. These people could persuade anyone to do anything and even commit suicide. These individuals often gathered citizens under some idea, attacked these citizens emotionally to break their will in order to gain full control over the minds of these people. These evil masterminds often attempted mass suicide in connection to some important “religious” date or even public holiday. People believed these individuals because of the promises of great benefits of dying or of simply belonging to some particular religious group and rejecting the rest of the world. After some time the perception of persuaded people was so greatly distorted that the benefit of simply seeing ‘the master’ was unsurpassed by any of the cost they might have incurred.
The cost of suicide also increases when considering public opinion about suicide: “What will other people think of me? “. Traditional thought would include God as one of “the other persons” who might have and express disapproving attitudes . Finally, attendance at religious services potentially gives individuals access to a support network. Those without a support network are most likely to commit suicide. The support network brings a lot of benefits to people, things like new friendships, affiliation, understanding. This increased benefits of life compared to benefits of suicide and made people change their mind to stay alive.
