Why would they kill Meghan. She's got nothing. She's a nobody…an extremely naive half-breed who thinks she's marrying for money and love. She will get neither. She's middle aged, she can't have children, and she has no path to the throne. She will do what she is told, or the marriage will quickly end in divorce. And she will be out on her ass in less than 60 seconds.
They're just glad to marry off Harry…to anybody at all, so he can stop embarrassing them.
ALTHOUGH…this wedding would be the perfect opportunity for the cabal to stage another FF. Very few of the guests who will be in attendance wedding would be missed.
Do it, cabal!
