Well I can understand why that would be hard to represent, but Atributing abstract nouns to concrete ones would make for interesting puzzles.

Have a rogue villain attacking NPCs? Whack Justice on him.
Proud, self important guard blocking your path? See how he fares against some Dispair.

Agreed, but it'd also create another dimension of complexity, from the creator's perspective, that would take another long while to implement.
Of course, you could accomplish the same thing (arguably) by summoning a 'hero' or 'superhero' instead of 'justice,' and summoning, I dunno, Medusa or Cthulhu instead of 'despair.'

Hence the game's awesomeness.
