Secret-Keeper Conundrum

It would seem that like so many things in the magical world, the 
Fidelius Charm is immensely powerful and has the potential for 
serious misuse. That's really not unlike a lot of things in our 
world, from the Internet to nuclear power to insecticides. We manage 
and control them with rules and a certain amount of personal 
morality. I think we can assume that the same holds true for the 
Wizarding World. There are undoubtedly rules for using charms like 
this, just like there are rules about becoming an Animagus. I would 
also assume that it's a complicated and difficult spell to perform, 
one which most witches and wizards wouldn't dare try. And I would 
assume that writers of fiction in the Wizarding world write suspense 
novels about terrorists who threaten to use these charms in terrible 
ways and heroic but renegade Ministry witches and wizards who defeat 
them in exciting, somewhat implausable ways.
