Yeah, taking in Syrian refugees would surely be a great idea for Israel 
If people who want Israel to be destroyed as a Jewish state in the first place are mad with some Likud policy, then it's no big deal.
Well if I was a Syrian refugee who didn't have a negative opinion of Israel up to this point, I certainly would feel differently after being denied the ability to seek refuge from ISIS there.
I doubt Israel is going to care about alienating a dozen or so Syrians who didn't hate Israel beforehand. Considering that the conflict will probably drag on for the foreseeable future, it makes sense to put refugees in places where they can conceivably become permanent residents. Israel definitely is not one of those places.
