Yes!  It says that you'll kill those who disable the option, but
that's not itself a reason to be completely unable to turn it off.

Just think of it as a good way to increase your reputation as a bounty hunter ;)

Seriously though, I agree it's a terrible idea to turn this off in
general, but really that's not a reason to make it impossible, as it
does still have value in very specific cases.  You can still disable
CONFIG_BUG, for example.
