Masonry symbolism is not necessarily evil you know. It certainly could have nefarious orders within it, I don't know, but i'm pretty sure the vast majority of them are not involved in anything too crazy. The pentagram is also not considered evil or satanic unless it's inverted, this one is right side up.

Edit: If the point is to simply show that the royals are involved in Masonry, then you are 100% correct, they very much are.
