Well, he was the winged horse who helped a Greek hero slay the Chimera, but later accidentally killed the hero... Pegasus didn't intentionally do either thing, though. I guess he brought more good than evil to the mortals.
Only evil.
Mostly good but some evil as punishment.
He brought Good
Apollo gave evil to humans because he would slaughter them
Aphrodite was to bring both good and evil to humans to show them love and effection but to also break hearts and give undesireable feelings
Good! She gave them each love.
She brings good by giving the humans crops, seasons and a good harvest.
In all Greek Gods is the potential for both.
He brings good when he is in a good mood otherwise when he is mad he brings storms and earthquakes who could injure or kill humans.
Poseidon brought good and evil to humans. But one good thing he did while he was in a good mood id build islands for people.
In Greek mythology, Pegasus is often associated with being a symbol of wisdom and fame, and is generally depicted as a noble and benevolent creature. Pegasus is commonly seen as a positive figure, representing grace and beauty.
Good, of course.
