A little dark for Nick?

I watched iSell Penny Tee's and Freddie had a thought of killing Sam with a knife. What the heck? That's mean. Also in iGet Pranky there's Carly saying that she was going to suffocate Spencer with a pillow till he stops kicking. I know that it's supposed to be funny but little kids watch this show to. I think it won't be funny to see little do that. Great thing Freddie stoped himself for having those thoughts. Carly didn't even apoligize for threatening Spencer. Like Spencer says 'that's some pretty dark stuff.' Was it dark or not for Nick? I need opinions please.
