Hmmm... probably try to make it feel comfortable around me, then try to get the trap undone. If the hunter did show up, and, depending on the area, i'd remind him it's illegal to hunt or trap wolves, and that i've just finished calling the local authorities...
SOmething tells me though, he'd have gun... and then i'd remind him it's illegal to kill someone.
Him: "But it's not illegal to kill a freak like that thing."
Me: "Really? Well then, what proof do you have that i am a freak?"
Him: "You're standing by it..."
Me: "I just came walking through the woods. It was a nice day out and i figured with it being this close, i might see what the forest is like."
Him: "Fine... whatever... but i'm not letting that thing get away."
Me: "It's a wolf."
Him: "It's a monster..."
Me: {throws rock at hunters head and sets creature free.}
Him: "Why you...!"
Me: "It's gone... which means you shoot me, you won't see sunlight for a long, long time."
Him: "You... {long list of profanities} you let a murderer escape!"
Me: "Really? What'd it do, kill a dairy cow?"
Him: "That {bleep} killed my son!"
Me: "Doubtful... that wolf looked more likely to run away from a human that attack it."
Him: "That's not what my son said. I told him not to get involved with them."
Me: "Okay... i'll be leaving now." {slowly walk way, leaving the hunter to stare back at the forest with an angry and sorrowful look on his face}
End scene
Hmm... depends on a lot of things, but i would probably try to get the creature free first... and all you have to do is switch out who/what the wolf killed and it works... unless it was actually a dairy cow...
If it was a passerby, i'd just say i was trying to help the wolf.
Eh... just like RedEye to suddenly make me think of a story line...

No what you have are bullets in the hope that when your guns are empty I'm no longer standing. Because if I am, you'll all be before you've reloaded.
