Harry could without being tainted by it.  That's speculation, no?  I
mean, not the part about Harry -- we can gather than Harry wasn't
tainted (in the sense of being seduced, long-term, by the Dark Arts).
 And yes, DD gave into the seduction of the Hallows.

truly because he was scared to, or couldn't bring himself to for fear

McGonagall said -- that he was "too noble," or, put differently, that
he simply chose not to? <snip>

Carol responds:

Doesn't Dead!DD say in "King's Cross" that he was permitted to use the
Elder Wand because he won it from Grindelwald, but not to kill with
it? My sense of that passage is that he's afraid of being seduced by
the Elder Wand itself, of becoming another Voldemort or Grindelwald if
he uses it to kill. He may have extended that self-prohibition to any
other Dark spell, particularly the Unforgiveables. And certainly,
given his prowess with that wand, he had no need to perform Dark
magic. He could defeat anyone, even Voldemort (who resorted to
possessing Harry when he couldn't outduel or kill DD).

It's canon that DD fears the seduction of power, which is why he
refused to become Minister of Magic. It's also canon that a wand forms
a bond with its master. If he used the Elder Wand to kill or torture
his opponents, his scruples would erode away, and he'd probably accept
the position of Minister as well. The temptation to be a second
Grindelwald might be too much to resist.

Carol, who wouldn't trust Dumbledore anywhere near the One Ring
because he's more like Saruman the White than Gandalf the Grey
