The Bishop or Rouen defeated a Gargoyle with his crucifix....after burning the body only the head remained which was put on the church to scare away other demonic creatures. The tradition continued in many buildings today.
Now Bethel has these creatures on buildings like the Bossert Hotel....yet Sparlock is Evil and must be removed??? With Millions of dollars at stake I guess a little demon next to "THE WATCHTOWER" sign is okay.
