Is the world better off with or without Islam?Watch this thread
Virtually impossible to answer because of the countless factors
But what we don't need is terrorists.

You shouldn't just be asking this about Islam. At times, I ponder if the world could've been better off without Christianity. Even now, the only religion I can feel any compassion towards these days is Judaism.
In a world where people are more educated and free to draw their own conclusions based on facts and solid evidence you will of course get evil people doing evil things but there will be no predefined doctrine as a basis to go from. They will simply be lone rangers, unless groups form and create a collective identity which is very likely given historical events.
