Even today people don't see a King as equal, because so many are infatuated with Royalty and look on it admiringly.Certainly, and it was visceral back in the day, but more for the religious than civil implications. Killing Charles I was wrong not for its act of regicide but for the deicide, as Chuckie was head of the church. (Under a pope, kings were expendable, but if the king represented God, uh oh.)
That's for sure.
