You make a really good point and have caused me to think about this more deeply! I think to answer the question I need to start by researching why Christians stopped being animated by the violent passages of the Bible, and only subscribe to the (relatively) more benign ones (generally). I think the point I was actually making (albeit inadvertently) is that as long as Muslims believe the full text of the Quran is actually true, they will be motivated to violence (yes it may require some charismatic person to push them, or some sort of social encouragement, but that person or group also generally believes in the text of the Quran). In contrast, someone who subscribes to Jainism could never be animated to commit a violent act rationalized by their religious text, because Jainism is against all forms of violence. TL;DR - The content of the religious text matters, even if other factors are also at play.
