No, but murdering your wife for what in civilized world is considered nothing based on your religious views makes a religion horrible. Cutting people's heads off as part of your culture (your culture being heavily based on your religion) is horrible. Castrating corpses as part of your culture, is horrible. Harvesting people's organs is horrible. Flying planes into skyscrapers is horrible, capturing an elementary school, killing a man that was trying to calm down the kids and then taking up 12 year old girls to the second floor, raping them, killing them and dumping their bodies out of the window into the crowd there their parents are is horrible. On the off-time from killing infidels cutting off heads of your own people because someone's grandfather couldn't divide a sheep with your grandfather is horrible. Making 80% of the world's cocaine is horrible.
I can go on and on and on. You people are just a bit ignorant, you never met those people face to face, to you they are only what the TV or the internet tells you. Imagine this, there are people out there those brains work completely different from yours, the life you know, the values you hold have completely no worth to them. Now I'm sure you're gonna all start telling me about how you know everything because you live in or near a ghetto, but thats just not the same.
If you insult them they will smile and then stab you in the back (literally) then you turn around. If you're weaker than them they'll do whatever they want to you, if you're stronger than them they'll get on their knees and start begging you to not do to them what they do to those who are weaker.
All that said I have met two of them in my life who were decent human beings, but big picture wise those were just exceptions to a rule.
