What I find particoularly annoying and interesting, is that most of those "silly/dumb" social network questions are engineered with at least 2, sometimes more layers, for the purpose of getting a reaction not really from the "dumb people" but also, possibly mostly, from the smartass that can't help point out something they think they noticed, incongruity and the likes, unaware that those are there on purpose to bait them in.
This case is a lot more blatant, possibly fake, but the "controversial" interpretation of stabbing one of the children is not an afterthoughts of the sick mind of us memers terminally online, it's probably the core reason the thing has been shared and worded that way.
I just hope my own reaction has not been 100% predicted.
