As Hal Jordan says,
Fear is the enemy of will
(Justice League - Doom 2012)
This is, as far as I'm aware, a recurring theme across DC continuities. The Sinestro Corps (or Yellow Lanterns) has a significant advantage over the Green Lanterns because fear neutralizes willpower. (Please correct me if I'm wrong, of course.)
But fear and will are not the only emotions to fuel lantern powers. There is also rage (red), greed (orange), hope (blue), compassion (indigo), and love (violet). Do any of these pairs have a similar relationship as will and fear, where one has an advantage over the other? Which one, if any, has an advantage over fear?
