Quote #4
"… the wand would be bound to attract trouble –."
"Only if you shouted about it," argued Ron. "Only if you were prat enough to go dancing around, waving it over your head, and singing, 'I've got an unbeatable wand, come and have a go if you think you're hard enough.' As long as you could keep your trap shut –."
"Yes, but could you keep your trap shut?" said Hermione, looking skeptical. (21.57)
Hermione brings up a good point here – one of the greatest dangers of having a ton of power is the temptation to brag about it and thus get yourself in more trouble than said power is worth.
Quote #5
If only there was a way of getting a better wand…
And desire for the Elder Wand, the Deathstick, unbeatable, invincible, swallowed him once more… (22.55-56)
Even Harry wonders for a moment if more power might be the answer – the temptation of the Elder Wand is a danger to any wizard in a fix, even our hero.
Quote #6
"The Dark Lord no longer seeks the Elder Wand only for your destruction, Mr. Potter. He is determined to possess it because he believes it will make him truly invulnerable."
"And will it?"
"The owner of the Elder Wand must always fear attack," said Ollivander, "but the idea of the Dark Lord in possession of the Deathstick is, I must admit… formidable."
Harry was suddenly reminded of how he had been unsure, when they first met, of how much he liked Ollivander. Even now, having been tortured and imprisoned by Voldemort, the idea of the Dark wizard in possession of this wand seemed to enthrall as much as it repulsed him. (24. 156-157)
Mr. Ollivander's moral ambiguity is caused by his fascination with the idea of so much power existing in one place. On a certain level, he's more interested in the concept of the most powerful living wizard possessing the most powerful wand, even if it's used for evil, in a kind of scientific way.
