It is not Islam at fault...
...but petty small-minded men who have control issues in that they would control how all people think and feel even unto whether others should live or die. It is a sickness of the soul among a select group of people who should be wiped from the face of the earth. Do not read that as 'all muslims.' Only those who have that sickness and spread it to others.
Religion, whether it be Islam or Christianity or others, are used as a springboard for sick people to do violence on all who disagree with them. If they did not have religion, they would find another excuse.
