text: By this reasoning you should expand this to many other behaviors.  Many cancers are often caused by human behavior--lung cancer tobacco, skin cancer failure to protect against sun, etc.  Other major diseases are often caused by diet and lifestyle, for example many forms of heart disease, hypertension, and diabetes.  Many "accidents" are self-inflicted through risk taking behavior. Of course why stop at science.  Many evangelicals believe disease is caused by sin.
