Let's think this through for a second. How much would change if Harry 
went back in time to kill and/or stop VDM? Because, as Hermione said, 
you have to be very careful in time travel.

I went on to list a few of the changes as "pros" and "cons". I just 
realized that that was completely unnecessary. If this time travel 
thing were to happen, it would be to change something *in the past*. 
Which means that the present we are seeing would have already been 
affected. Take a look back at that section of PA. The "present" trio 
are hearing the same things as the "future" trio. Even with them not 
having travelled back in time yet, the present was different. Think 
about it.
