I'm curious how many people actually left Gren alone, by not tearing his arm off.
It seems a vast majority took the opportunity the moment it appeared!
Granted yes he was being a very big pain in the ass, flinging you around like a rag-doll and what have you. It wasn't entirely unprovoked, a lot of Fables are tired of being treated like dirt. Gren just decided to take a go at him even if it is indirectly his fault.
That doesn't justify it but it's not hard to see why he did it.
Personally I couldn't bring myself to do it.
Gren had already taken quite a nasty beating, he wouldn't dare strike back again, tearing his arm off served no purpose except to create more unjustified brutality.
He even curls up in a ball and is crying afterwards how can that not show you the guy was done, he was not gonna push his luck any further.
Aside from unlocking one of the story entries, what did you gain from tearing his arm off? Nothing!
Momentary satisfaction maybe, but that's about it.
Wondering if anyone else feels the same way.
