I don't think 
is a very good emoji, because maybe the facial expression is there but it's small and dark, and looks like a guy making a slightly-scrunched-but-essentially-neutral facial expression. A WTF emoji should have a big extravagant expression
Walter White did way worse tbh if we want to split hairs here (username: CoolerOpposide said, dripping with sarcasm)
i get the comedic sentiment, and the following isn’t aimed at you
to further clarify, other terrible people emojis here are used because they are terrible to mock them, this one bothers me because it’s proposed to be used a generic wtf and glosses over his child abuse and homophobia. Chan has this kid-friendly public image and got to star in an animated kids show for fuck sake while being a piece of shit and this feels like continued whitewashing. jack black gets more heat and attention here for being kid-friendly while libbing out but an actual child abuser homophobe gets a proposed ‘clean’ emoji trophy
