Okay, Cop. I'm not too sure if I can call my personal view a doctrinal one, though.
Imo, I think, in some cases, it is much better and wiser to allow the right to self-termination. As sad as this situation may be, I do think it is more moral to allow the need to end ones own life based on certian conditions.
The one condition for me is the condition where there is much suffering and where there is no hope of cure. In this situation, I think it helps that the one going through it is aware of that choice.
In other situations, where the person is viewed as a vegetable and with no hope of recovery, I find much harder to judge.
