Please explain why.

Somebody probably changed the tag type when tagging characters for an image inspired by or involving the seven deadly sins.

Should be easy enough to fix manually. A disambiguation to distinguish (character) from (emotion) might be in order, though.

KC: +1

I think there may be multiple characters who go by the name of Envy though, not too sure yet (not counting the general personification of the Sin not associated with a specific franchise)

envy was changed to a character type tag about 1 year ago because a character owner wasn't familiar with tagging standards, presumably. (see https://e621.net/post_tag_history?tags=character%3Aenvy) That post has since been changed, so the tag can be changed back.

Emotions are usually tagged as an adjective. So maybe that usage would fit better under envious...?

lust is also a character

If Envy and Lust are both tagged as characters chances are it's referring to Full-Metal Alchemist

Less likely it may be Oversexed Eeveelutions] but then there would be pictures of Eeveelutions under the tags

I made lust back into a general tag, and if we are to disambiguate it, I'd say the page should specify the general terms as "lustful", "greedy", "wrathful" "envious", "prideful" (avoiding proud because it is past tense, usually), "gluttonous", and leave sloth alone because it's not something you can see, and it's a species.

Mind you, all of these are technically unable to be seen, because they're states of a character and not necissarily visible, but it can still be tagged nonetheless when it applies.

Wonder if Envy from The Binding of Isaac would appear in the future...

I'm surprised none of the names mentioned in this thread are from the Pixar movie. But I did not see that movie.

Similarly (or should I make a separate thread?) test is aliased to tést, a character tag, although none of the (four) posts seems to have a character by that name which doesn't even make sense why would you need an accent on a one-syllable word it's English not a tonal language. One of the posts is obviously supposed to be "test" as in "academic exam" but the others I have no clue at all.
