Of course, but many witches and wizards oppose Slytherin's prejudice.
 Most hate Voldemort and all he stands for.  But the question is, does
the hypothetical Heir have any specific advantage in the fight against
Voldemort that your everyday, genocide-opposing wizard doesn't? 
Something that would prompt such a drastic preemptive strike?  Nothing
has been mentioned thus far. 

I also commented something along the lines of:

> Voldemort's main purpose has been to eliminate Muggles and
>Muggle-born wizards...

And someone mentioned offlist in a mail I accidently deleted before I
could accurately quote him or her:

> Longbottoms? Fawcetts? Boneses?

The Longbottoms were tortured by his supporters, while Voldemort was
in no condition to instruct them.  The Death Eaters have their own
motivations for their actions, not necessarily consistant with
Voldemort's ideas.  We know nothing about the Fawcetts and Boneses,
other than that they were victims.  That said, I never said Voldemort
opposed killing purebloods.  Voldemort killed pureblood wizards, but
these wizards were standing in the way of his ultimate goal: to create
a pureblood magic community.  His ideal could never exist if there
were these silly people clinging to Muggle sympathies.
