The free will argument demonstrates that christians don't understand free will.

Depends on what you mean by "better".

I'm sure there are many things in life that we can unanimously agree we wouldn't miss if they were gone.

A follow-up question may be whether subtracting certain things from the "programming" of reality would have other repercussions, but this assumes the creation's every event has to make sense in terms of some basic laws, which it shouldn't if the creator is omnipotent. An omnipotent creator could add a magical barrier that encapsulate anyone who's about to rape, even if it's an exception to the general laws of physics. But hey, some hip theists seem to think God is the Big Bang.
