As someone who lost a close family member to suicide I can tell you this, how they get there is irrelevant. The end result is that traumatizing part, gun, rope, car I still would feel the same. If my brother shot himself I wouldn't have gone and melted his and my guns down or blamed the guns for "causing" suicide.
Agreed. And sometimes, people just don't have the time and/or money to help loved ones. Some people cannot be helped.
