But panderverse Cartman calls panderverse Kyle a heathen as he’s obviously supposed to be South East Asian of some flavor. And Prime-Cartman calls Prime-Kyle a Jew several times before the swap. I think after that it doesn’t make sense to use the slurs as they don’t know about the cultural backgrounds of Kyle in their alter-universes.
Yeah, honestly, if this is supposed to be a “redemption arc”, it’s most likely only to set us up for him to fall even further. The hard part of making a character into a “monster” of a person, is that eventually it’s less shocking when they do something horrifying. If you make people think “oh, hey, maybe he’s turning his opinions around, and being less of a dick” and then slap them with that shocking behavior again, it lands much more effectively.
