This would make using the mark ring very cumbersome.  But if you
didn't have some way to turn off the mark, the screen would be
ablaze with light most of the time, because a number of commands
set the mark.  This is the main reason I've never been thrilled
with the idea of having the region highlighted.  C-x C-x is a
simple enough way to check the bounds of the region before doing
a kill.  As for accidental kills, I think the code posted by
Stephen Gildea is good way to provide a warning of what you just
did.  It's also a good start toward a more general facility.
