Relative terms depending on what the individual values.

Opposites?

Troll bores

Good in black abd white terms
A selfless person.
Evil in black and white terms a murderer who shows no sogbs of remorse.

Not conclusive but an example

They are both relative concepts based on social/cultural mores. In many places in the world I would be considered evil being gay, and atheist. (In fact even killed)
