These roles CAN overlap but they can also exist separately.
a villain needs to commit evil. They dont need to see it as evil but their actions need to be evil in some way. jack in this example though, is unapologetically evil with no moral nuance
an antagonist can be any moral alignment, just serve to get in the way of protagonist. The wolf is morally neutral. he is a force of nature personified.
Rivals tend to be somewhat close in alignment as the protagonist to an extent and seek to get the same goal through similar or different methods that challenge the protagonist own skillset. goldilocks is not necessarily evil, but has the same ethics that puss and kitty display putting her on the same ground as the protagonist.
my dad always sneezes at least twice in a row and i think i inherited the same volume of sneeze condensed into one because im firing shotgun blasts out of my nostrils. one time i asked my doctor if i should be concerned that sometimes i sneeze so hard that my left arm goes numb and she left the room for 5 minutes before coming back like

“The other is a low animal, about the size
of a little dog or cat. I mention it here, not on account of its
excellence, but to make of it a symbol of sin. I have seen three or
four of them. It has black fur, quite beautiful and shining; and has
upon its back two perfectly white stripes, which join near the neck and
tail, making an oval which adds greatly to their grace. The tail is
bushy and [163] well furnished with hair, like the tail of a Fox; it
carries it curled back like that of a Squirrel. It is more white than
black; and, at the first glance, you would say, especially when it
walks, that it ought to be called Jupiter’s little dog. But it is so
stinking, and casts so foul an odor, that it is unworthy of being called
the dog of Pluto. No sewer ever smelled so bad. I would not have
believed it if I had not smelled it myself. Your heart almost fails you
when you approach the animal; two have been killed in our court, and
several days afterward there was such a dreadful odor throughout our
house that we could not endure it. I believe the sin smelled by sainte
Catherine de Sienne must have had the same vile odor.”
