That's a different issue. Abortion has been legal in this country since well before any current doctors and nurses were trained. A new law about assisted dying would not have been anticipated by any of our current doctors and nurses and should therefore be a matter of conscience. It could be a different matter for those trained after the new law came in. We'd probably want to avoid a two-tier profession in that regard, however. It could also be a matter of which particular aspects of the dying process we would expect people to be involved in.
