Parker said following the tremendous success of "Mr Hankey, the Christmas Poo", much of the direct feedback he received for "Damien" was negative. Parker described it as the "first sort of backlash" he had experienced with "South Park", with fans claiming the show was losing its edge and that Parker and Stone had "sold out". Parker said, "We kept hearing that word so much. We were like, 'What does that mean, sold out? What did we get and what did we do?' We just kept doing what we thought was funny, we didn't go start making commercials or anything. But everybody was saying we sold out." Nevertheless, the episode received generally positive reviews, and has been described as one of "South Park" "classic episodes".
