Mortality of horcruxes?

ET here-

Been reading the "Of essence divided?" thread with great interest & 
it reminded me of something- 

I'm perplexed about the whole idea of having a living thing (such as 
a snake) or something like a scar as a horcrux.

Why would you put a portion of your soul into something that has a 
definite lifespan?  If Harry's scar is a horcrux, then why would LV 
be trying to kill him?  Wouldn't that be like LV trying to destroy 
himself? Or does LV regain that piece of his soul somehow?  What 
happens when Harry dies (of natural causes or otherwise)?    Or does 
being a horcrux confer some sort of immortality or longer lifespan? 

I guess I've always thought of the 7 Horcruxes as being like 7 
different banks that LV deposited bits of his soul in ,so that all 
his eggs wouldn't be all in one basket... Seems he'd pick the most 
secure things he could think of.......

Along the same lines, if Nagini is a Horcrux, wouldn't LV be a bit 
more protective of her?  LV asks Wormtail where Nagini is (in GOF)and 
Wormtail replies that he's uncertain(says she's exploring the 
house,... maybe)  LV doesn't really get bent out of shape over it.  I 
know he can give Nagini orders, but at that point, he doesn't know 
where she is...and they're at the Riddle house then which is in 
Muggle territory.  If you're a Muggle and you come across a snake, 
won't you try to destroy it?  So if Nagini had a piece of LV's soul 
in her, wouldn't he want to know where she was?  At that point the 
diary had already been destroyed, so he knew he was one down anyway...


I hope this makes sense...I'm pretty muddled on it myself to be 
trying to present it to others.
