Should societies allow suicide?   stance: no:
No. The suicide (particularly of young people) is not only a drain on the country (education and the like) but also means the loss of the potential contributions that person could make to society. Others are probably going to argue that if people really want to end their life then it is cruel to keep them alive. I disagree. People can change their minds about these things. I think more work and thought (not just money), should be put into suicide prevention. Suicide is a trajedy we CAN prevent.
