The Quran and Islam are wrong about pretty much everything in it as a description of reality. People who choose to follow it in my opinion are misguided misinformed and deluded. what they are not is murderers waiting to happen.
Near as I can tell no one is claiming that. The claim is that people who opt to follow Quran and Islam are more likely to become murderers as a result of these texts and beliefs than an (hypothetical) otherwise identical person who is not following Quran and Islam.
