Here’s the practical answer: they’re provocative, but whether they’re “blasphemous” depends on your religious standard rather than on a single objective label.

Quick take

  • Hazbin Hotel gets called blasphemous more often because it personifies Heaven, Hell, angels, and demons in a way that some Christians see as irreverent or theologically offensive.
  • Helluva Boss is usually seen as less directly blasphemous and more broadly vulgar, irreverent, and adult-oriented, with religious material mainly used as part of the setting and satire.
  • Some viewers argue the shows are not blasphemy because they are fiction and do not claim to be religious truth.
  • Other viewers say the shows cross a line because they portray spiritual beings and afterlife concepts in ways they consider disrespectful or unbiblical.

Why people react strongly

A lot of the controversy comes from the shows’ tone: they mix demons, angels, redemption, and moral commentary with comedy, profanity, and violence. For some religious audiences, that feels like mockery; for others, it reads as fantasy worldbuilding with a rebellious edge. The same scene can land as satire to one person and sacrilege to another.

Which is “more blasphemous”?

If someone is ranking them, Hazbin Hotel usually gets the harsher reaction because it deals more directly with Heaven-versus-Hell themes and makes redemption and divine authority part of the plot conflict. Helluva Boss tends to be judged more for vulgarity, crude humor, and violence than for theological offense, though it still has religious imagery that some people object to.

Viewer perspectives

“It’s just a TV show” is the core argument from viewers who do not see blasphemy here.

“It humanizes hell and disrespects heaven” is the core argument from viewers who do see it as blasphemous.

Both reactions are common online, so the answer is less “yes or no” and more “who is judging it, and by what beliefs”.

Bottom line

If you mean strictly from a religious viewpoint , many believers would call parts of both shows blasphemous, especially Hazbin Hotel. If you mean as a general media label , they are better described as irreverent, adult, and satirical rather than simply blasphemous.

TL;DR: Hazbin Hotel is usually seen as more blasphemous than Helluva Boss, but both are controversial mainly because they use Christian-coded imagery in a very irreverent way.
