Another reason for executing Shaykh An-Nimr: the revenge factor

There is a factor of personal revenge in the execution of Shaykh An-Nimr.  When Prince Nayif died, Shaykh An-Nimr expressed sympathy with those who expressed joy at the death of Nayif, and then elaborated on his crimes during a speech.  Prince Muhammad bin Nayif sought revenge and got it.  That is who those tribal and atavistic House of Saud princes think and operate.
