Elf Beheading?

Okay.  I've been tossing this idea around in my head since I read 
OotP the first time.

Now, all of the Black House Elves are beheaded when they become too 
old to be useful ("too old or infirm to carry a tea tray" is a 
paraphrase of the line).  

I postulate that Kreacher was too old to be useful.  He didn't do 
any cleaning.  He wouldn't obey Sirius (the only remaining Black).  
(I don't remember any mention of Kreacher and tea trays, but I don't 
think he'd have been capable of holding one steady for the current 
inhabitants of Grimmauld Place.)

So.

Why not behead him?  

Everyone (except Hermione) ends up happy.  

Kreacher gets the highest honor he can perceive.  Sirius doesn't 
have to listen to Kreacher's poison anymore.  Molly can clean house 
without Kreacher getting in her way.  They can all finally just nail 
the stupid curtains closed over the Old Bat and never have to listen 
to her again.  

Sure, it's taking a life.  But wouldn't it also be a kindness?  
Kreacher's *not* happy at all.  Wouldn't it be kinder to him to ... 
put him out of his misery?

What do you all think?
