Its quiet unfortunate for you to say such words.If boko haram did something horrible,it would'nt affect ISLAM or the MUSLIMS,cos the religion islam stands on his own.Your mother can not be responsible for your actions even if she try to guide you from evil.You are responsible for your action,whatsoever.So,if out of anger Boko-haram did something horrible,they are on their own,it does  not affect or have anything to do with the teachings of Islam.Allah said ih the glorious Quran

 Do not consume one another wealth through unlawful means,instead do business with mutual consent,do NOT kill yourself by ADOPTING UNLAWFUL MEANS.Indeed ALLAH is merciful to you.           QURAN 4:29.
So you see, a true muslim will never involve in atrocities,chaos,sabotage,destruction,massacre, and all act of unlawful things.
   However,everybody have fall prey to boko ha ram including the Muslims.May Almighty protect us from the hands of the Evil ones .Amin.Rammadan Kareem.
