The wizard did a very logical, Reasonable thing.
It's been pointed out that sure, the character could've been True-Ressed, if disintegrated. The Wizard probably knows this, too. So, the option is either A) Kill him, and POOf, he's back lickidy split, or B) Keep him alive, but reduce his utter effectiveness, so that he may be alive, but he's sure as heck not going to be as dangerous.
This Is Not Pulling Punches. Really, that's an effective use of a spell, if you ask me.
If Death is not something to fear, then use something else to put Fear into them. When Death is but an annoyance, then something else needs to be a concern, or There *is* no Risk.
Let us consider the situation where a mage is flying over a battlefield, where grounded baddies are trying to kill him. Their ranged weapons aren't hurting him. So, what's the reasonable thing to do? DISPEL the flying effect, so the wizard comes down and is wackable.
Consider that same example, where a wizard is flying over the battlefield, and being shot by archers. Sure, he can Kill the problematic archer, but instead, he nukes the blow, and flies over the group, mooning them, taunting them, then flying off. That's more satisfying. In one case, you have people who want you dead for killing their comrad, not to mention a comrad who will want you dead for killing them. In This case, you just erked them by hampering their ability to kill you.
Also something to consider. Now, I don't have the rules in front of me, but when destroying an item, you use the character's base save, right? So, they would use the fighter's base fort save. Now, this is the BASE save. Not upped via magical items, or con. So, really, if it doesn't use the con bonus/magic bonus, it's easier to destroy.
