Joker breaking in his new henchman with horror and seeing how far he'll go before he questions it is a very real tactic gangs and criminal bosses use to encourage fear and loyalty in underlings.
Like if you don't like it, fine, absolutely, but it doesn't have that dissonance that, say, Identity Crisis has.
