This is a disaster waiting to happen.

Look how blasphemy laws are used in Pakistan for example. They are used to persecute religious minorities and to settle scores.

Blasphemy laws are not needed. God is omnipotent, all seeing and all knowing. He created the universe and everything in it and he is not insecure that he needs humans to punish other humans for perceived insults. He's a big man and he can take it.
