@CorvoAttano long (very long) story short, he's the main enemy of Hal Jordan. He used to be the greatest Green Lantern there was, trained Jordan when he got recruited, but eventually turned to the 'dark sidecar, or rather the yellow side here; the Yellow Lantern Corps was more or less created by Sinestro, which is their oath include Birn like my power, Sinestro's might
Sinestro was also the ruler on his home planet, Korugar, but used the Green Ring there in ways that made him a dictator. That goes against the way the Green ring should be used. Arguably though, he was trying to do "the best" for Korugar.
Also, Sinestro has a daughter, Soranik, who's featured in the Rebirth series. Not to spoil, but she basically was a Green Lantern, and had her days as a Yellow too. The rest you'll read in the Rebirth run ;)
Soranik is the daughter of Abin Sur's daughter (or sister?); Abin Sur was the alien whose ring chose Jordan when he died, and was also the mentor of Sinestro. Soranik used to be one of Kyle Rainer's girlfriends.
I think that's enough "general info" on Sinestro to understand what's going on in the Rebirth run :)
@CorvoAttano no Gamma Lanterns that I know of.
@CorvoAttano the Green Lantern Corps is indeed the biggest. I think there are like, 5 000 Green Lanterns? This is partly because there's one Lantern per sector and they act as space cops, hence the numbers. The other Corps don't have as much members for various reasons, the main one being that they were "created" by DC fairly recently (less than 15 years). Some corps can't really have more than one member, like the Orange one, which is Greed and not sharing ;D
@CorvoAttano there's no really "good Lanterns and evil ones". Sure, most of the time the Green ones are upholding the law but every once in a while you have a rogue. The Lanterns aren't based on your ability to respect a law, just on how much you can feel of emotion XYZ
For instance, one might think the Reds are evil. Well, they are powered by rage but don't always want to go and destroy the world. When you look at them, they're victims first: Dex-Starr was thrown in a river, Bleez was sold as a slave and nearly raped, Atrocitus had his family killed by the Guardians (indirectly...)
Pink ones, for Love, sound like innocent gals right? Well no. Star Sapphires are bit- no really, they can be like super evil.
Etc, etc. Granted, I don't think I ever saw an evil Blue.

What should I do...
@CorvoAttano what do you mean?
@CorvoAttano which ones? Also, yeah, for the most part Rebirth Justice League is... Not good.
@CorvoAttano what Alex said, but in this case I'm pretty sure the Vertigo tag wiki already explains the relationship with DC and comics. At least, it should.
And in any case, people peer review and add them ;)
