the verb "hurt," whether transitive or intransitive, implies past tense....no need for the "ed." Moreover, hurt as a noun never gets a tense.
That's my #1 pet-peeve with grammar; a close second is when people write "it's" when they don't mean it is, but rather the possessive of the pronoun.
Sorry, I hope I'm not coming across as an ass; just annoys me.
