10 Worst Things The Green Lanterns Have Ever Done
5. Creating A Weird Class System - Various Comics
The entire premise of the 'upper class' of the Green Lanterns - known as the Alpha Lanterns - is legitimately one of the most messed up things to be found happening in a supposedly heroic faction.
Alpha Corps are forced to leave behind all aspects of their 'prior life', including their loved ones, and then go under a weird and awful looking surgery that supposedly helps them interact with their ring's powers better, although by all means this did appear like just a particularly brutal hazing regime.
Worse yet, this hierachy would later be used by Cyborg Superman to take control of the Green Lanterns from the inside, by turning many of their Alpha members into cyborgs that he could control, essentially allowing him a monopoly over the faction, meaning that this also allowed for countless deaths and a hostile takeover to happen.
