Israeli Christian charged with murdering his teen daughter over relationship with Muslim

How do you know that "...a lot of people, including some people here [RP] have fallen into the that trap that because some of the people who [do] terrible things are Muslims that all or most Muslims are bad people..."? That's a pretty serious charge and I can't say that I've seen any evidence of such a proclivity. Of course, that sort of reprehensible behavior is beyond my ken because I don't practice it. Are you that sort of person? Is that why you anticipate the worst in people?

The difference is how many Muslims use their religion to excuse their behavior, Christianity routinely denounces actions like this as terrible, to few Muslims condemn these actions while many, many other's hold fast that the father was within his rights as the girls father. (obviously this is more pronounced in the radical middle eastern countries then we see in the westernized Muslim communities) The foundations of the religion also make a huge difference, you won't find anywhere in the New Testament where this is encouraged, you will find many instances in the Hadith.

Actually what it shows is that bad people will do bad things, no religion required. But, to get otherwise good people to do bad things, religion, ANY religion, makes that a whole lot easier.

The fact is, religion is the most dangerous thing we humans have ever invented.
