Batman and Brainiac 2 (The leader of L.E.G.I.O.N. and R.E.B.E.L.S.) were both selected to join the Sinestro Corps.
Batman was rejected on a technicality (the yellow ring could sense that he'd recently worn a green ring) and Brainiac 2 got kicked out for refusing to follow Sinestro's orders.
I know batman got picked but his whole thing is scaring bad guys.
I was mostly wondering if a yellow lantern could function as a green lantern. You know, normal person who uses their power for good. Batman counts but hes more sinister and you could argue hes a villain for villains

Does the Corp exist in the multiverse? What does Earth 2 Corp look like?
James Howard
They worked together for a while actually. Guy became friends with Arkillo
Daniel Bennett
He's brown inside, even if that race has bred themselves paler as to insidiously infiltrate the country.
Mason Perez
Yeah, it was actually a recent thing in the Morrison run.
Soranik gave yellow rings to Harley, Wonder Woman, Flash and a few other random heroes to help fight off some space cultists that were attacking Earth. They seemed fine.
Ryder Rodriguez
I know. I like arkillo. But hes not really a good person. When he first shows up isnt he murdering people in a space ship?

Getting a ring and being able to use it to its fullest requires that it be worn by someone that people are genuinely terrified of. Being able to make people scared of them is one of the main attributes which is why monsters, psychos, supervillains, and dictators get them most of the time. Not many heroes work on the everyone must be scared of me premise outside of Batman, who apparently sucks at using a yellow ring both times he tried.
