They think they are, but they really aren't.

They are just born into an environment where they grow up being brainwashed to think this because it's an easy way to get them to follow you, the true motivation is and always will be power.

The teachings of the Quran do not teach anyone to kill for Allah, extremist people teach other people this to gain their support and following.

I just dislike seeing Muslims being associated with this at all because millions of them live in places like United States and a lot of people have poor thinking and will think all of them are like this when they aren't which is why it is best to just not say it at all.

If they were killing in the sake of Allah then they would not kill Muslims who believed in Allah like they do.
