I'd be more scared for Craig's safety if this was Moira or Kim making the offer because we actually know they have the bottle for this sort of thing as they've done it before.

but Cain has proven time and again he doesn't have it in him a few years back when he thought he'd killed Joe Tate he mentally fell apart and he threatened to kill Al for months and months but when he had him alone in the barn with a gun on him he didn't pull the trigger and Kyle had to step in and do it.

even Caleb when he and Cain were bickering called Cain out on his BS empty threats so if the show as realistic Sam would hear Cain's offer and he'd burst out laughing like honestly Cain's become like a chav teenager who tries to act like he's some dangerous big man.

but when push comes to shove he can't actually do the dirty work to prove himself I really wish the show would just drop this side to Cain he can still be a local tough guy just stop having him act like he's capable of murder when he so clearly isn't its especially crap considering his wife and his young son have both killed someone yet he hasn't.
