Firstly, more full stops! And Morgause had to survive because, firstly, when she was knocked out, it was similar to how Gwen knocked Merlin out in A Servant of Two Masters, and it'll be all unreasonable. Secondly, they needed someone to be sacraficed to open the veil so it makes sense in needing someone's death to close the veil, meaning the Lancelot wouldn't die and him having the affair with Gwen (which is really important to the story).
