I know and fully assent to the Church's teaching on ѕυιcιdє; that it is a mortal sin. However, what exactly is ѕυιcιdє? What is sinful, and what isn't?
Obviously, things like hanging oneself or throwing oneself off of a bridge are clearly ѕυιcιdє and are sinful, as are things like physician-assisted ѕυιcιdє. But what about other things?
For example, what of an old person saying that don't want any more medical treatment, which is necessary for their survival? Taking it further, what of a person with unhealthy or dangerous habits that, over time, will likely kill them? In both cases, I don't think the people necessarily want to die, unlike the clear cases of ѕυιcιdє above, but the end result is that they are, in fact, causing their own demise.
What does the Church teach?
