Apollo gave evil to humans because he would slaughter them
Apollo brings good
Only evil.
Mostly good but some evil as punishment.
He brought Good
Both, Artemis could kill or heal (with her arrows) women, as Apollo could (with arrows) kill or heal men.
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.
It really depends on how you look at it. He is the God of Thieves, but he uses his powers for good instead of evil. For instance he might of stole Apollo's cattle but he sacrificed two to the gods. He kinda does one bad thing and then does a good thing to set it right.
