More on time travel

No: HPFGUIDX 9323

I know that my first post on this was confusing. I think I can make 
it a little more clear. Then again perhaps not...

I've often read books that dealt with time travel and I usually come 
away totally muddled.  Then again my brains not the best place to be. 
Their either coming or going and usually going.

It seems to me that the time travel in the HP canon can't actually 
change things. Take for instance what seems the most obvious possible 
change that no one seems to have mentioned. Why can't they just go 
back and kill Tom Riddle before he becomes Lord Voldemort?  

But then I thought about it. Lord Voldemort would have happened even 
if there had never been a Tom Riddle.  Someone with enough greed and 
thirst for power would have been in his place. It seems to me that 
this (and examples of it throughout history) are problems with 
society as a whole. If we don't stand up then we're bound to fall.  
The wizard society must have been very vunerable. They needed a 
leader, someone to turn too. Voldemort happened to have to fill the 
position. 

Some things are predetermined. Even if Cedric hadn't of died that 
night innocent lives would still have been lost. That's enevitable. 
The time turner and such can affect some things but others, at least 
IMO, will work out no matter how we humans (and in this case wizards) 
try to change them.

Does this make sense?
