Sorry, but it's just plain wrong for a nun to involve herself in a deliberate sin and in the scandal of publicizing it.
Who made the decision to call in the Telegraph and publicize this story? The young disabled man? The nun? Somebody else?
I am not going to criticize this young man, unless it was his idea to call the newspaper and make this business public. We don't know that he is Catholic--probably not. We don't even know whether the nun in question had the power to say yes or know to his request. But the nun was stupid to let herself get involved in the public and scandalous perception that she approved of this business and maybe approved of publicizing it.
Let's hope she was just stupid--that the story got out because someone leaked it, and not because the whole thing was some kind of crazed publicity play intended to undermine the Church.
I don't think so, the man is pictured on the home page of the hospice's web site.
But this Sister is associated with the Church of Scotland, not the Catholic Church, thank God.
Most excellent questions.
