Yes. Once the cost is paid, you can resolve the effect as fully as possible.

"If the card put into your drop zone is 《Darkhero》, destroy an item on your opponent's field, **and** you gain 2 life."

Because it says "and" you would gain the 2 life, even though the item was not actually destroyed. The same would apply to Immortal Sword, Durandal or Unmovable Steel Mech, Ganzallar.

Were the effect to say "if an item on your opponent's field is destroyed..." then the 2 life gain wouldn't proc.
