Yeah, they're gross.
But in his defense, as a kid I had this recurring dream that was like this, but instead of smurfs it was just small baby creatures. I didn't torture them, I just played with them in a giant doll house. When I woke up, I'd always be hot and bothered.
This is the reason I never really judge people for their fetishes or kinks. Did I want to diddle babies as a kid? Of fucking course not. But I couldn't really control the dream, or the weird urge. Besides, since the want is obviously fictional, I let it be.
