The idea concerning suicide and euthanasia. Thomas Aquinas, circa 1225-1274 CE, collected a traditional Christian idea concerning suicide. He criticized aiding and abetting suicide as well as committing suicide because:
Suicide trample on instinctive desire that wishes to live
Suicide make others lament
It is only God that gives life and it is only God that can bring it to an end
Michael de Motague, 1533-1592 CE, was the first person of the Europian writer that oppositted the idea. He wrote five essays arguing that suicide can be interpreted as an option of people and that it is inevitable in certain situations.
These two basic positions remain essentially unchanged today.
