> I accidentally euthanised my father

Oh my god! That is horrible, and you are absolutely not to blame in any way. From the way you tell it, the instigator was the nurse. At the bed-side of your dad in a coma, you are in no shape to rationally process what is going on and grasp the full meaning of the questions; and in fact it took you years to "connect the dots". The nurse knows exactly what morphine can do and what are the limits on dosing; she had the dots all connected.

You must rid yourself of the every last trace of blame; to be caught in the flow of events does not imply being the root cause. Start by taking back the sentence I accidentally euthanised my father. It isn't true; you didn't do that, accidentally or otherwise.

Have a great day!
