OOP:Death--Point or Pointless?

I'm a newbie here and I've spent the last week reading these posts, 
enjoying reading the theories, etc (I can't discuss with my husband 
because he's only just started reading the book and has begged me not 
to reveal anything).

Regarding Harry dying at the end, part of me thinks this is a red 
herring on JKR's part, but another part of me thinks that perhaps 
this outcome is likely - the last word of "scar" that has already 
been revealed could mean that the scar might disappear with the death 
of Voldemort and the evil it entails, or perhaps LV is successful - I 
don't know if anyone has read "The Belgariad" by David Eddings, but 
when one of the characters die, that character is restored to look 
whole again, but is definitely dead (I won't reveal who in case 
anyone is reading the series).

However, with regard to the death of Sirius (am I allowed to write 
that under this heading?), JKR could be telling us that some deaths 
are pointless, or my theory is that if he survived, LV would have a 
huge weapon to lure Harry into danger (sorry if anyone else has 
thought of this, I've read so much this last week that my mind is 
buzzing).  Harry loves Sirius and regards him as a father figure and 
would do anything to help protect him - of course other characters 
are in a similar boat with relation to Harry, but Hermione and Ron 
are under the protection of Dumbledore after all.  Another theory is 
that Sirius was a reckless man who could lead Harry into danger - it 
seems that he regarded Harry as a reincarnation of James, but Harry 
has his mother's calmer temperament rather than his father's rash one 
(although of course, Harry does have his moments).

And I guess thats my two knuts - hope it makes sense.

By the way, my theories on the last two books, I think Ron is more 
likely to betray Harry than Neville or anyone else - I think Ron's 
jealousy is getting worse, which is why he has been made prefect - he 
can be something Harry isn't and in some ways he can protect Harry 
from himself, and also to protect Ron from himself.
