heh... uh no. given how they use rage to BURN EVERYTHING THEY SEE TO THE GROUND.
There is no Emo Lanterns.
Red Lanterns go around trying to quench their thirst of rage, only to never fullfill themselves given that the Red Lantern ring can not be removed normally. There has been only three times when a Red Lantern ring has been removed.
1. The use of a Blue Lantern ring to give the target red lantern HOPE can help remove the ring off of the user. BUT, it has to be from the user's choice to remove the ring.
2. The giant green lantern planet Mogo used small micro organisms to purge the Red Lantern Blood from Guy Gardner allowing him to remove the ring, however this did not full cure him of being a Red Lantern where he is now the current leader of the New Red Lantern Order after Atrocitus' death. [only for him to comeback... shit.]
3. And finally in the NEWEST issue of Green Lanterns 2016 issue 3, Simon Baz the new green lantern of Earth cured Bleez temporarily of her rage. He did this with sheer WillPower. However she did not remove her ring nor is her body purged of the red lantern blood, so after getting blind sided by Simon's Green Lantern Rookie Partner, Bleez went back into her full Rage Mode. shoot.
