Unless you are Japanese, that’s probably not the prevailing culture. For the vast majority of people suicide is seen as a mental illness that should be treated, potentially by force, not as an individual choice. Because a person suffering from mental illness by definition does not have full agency over their decisions. Even the idea of allowing suicide for terminally ill people is controversial (although it’s something I personally support).

In the past, suicide was viewed as immoral and criminal. We have moved past that, not because suicide is more socially acceptable, but because of a desire to more easily help people suffering from mental illness.
