One guy? From Boko Haram...
This Islam angle which you reply to is not really restricted to that one guy.
The entire organisation has co-opted and twisted religion in some way and it's a driving force for them, not just a label they pay lip service to.
Shekau has said “It is Allah that instructed us. Until we soak the ground of Nigeria with Christian blood and so-called Muslims contradicting Islam. After we have killed, killed, killed, and get fatigue and wondering what to do with their corpses — smelling of Obama, Bush and Jonathan (Nigerian president Goodluck) — will open prison and be imprison the rest. Infidels have no value.”
