10 Worst Things The Green Lanterns Have Ever Done
8. Not Teaching Them A Code Of Conduct - Various Comics
The topic of diplomacy is a tricky one when it comes to the Green Lanterns. While it's undeniable that each member of the team is naturally going to do things in different ways - as their powers work best when they truly believe in themselves - the fact that they are never given so much as a pamphlet on how to handle non-violent aspects of their job is pretty shady, all in all.
This is the one key flaw of the Lanterns themselves: they're in no way trained in how to react to specific situations, because not everything they have to deal with can be resolved by punching it really hard.
Given many of these Lanterns are forcibly embroiled in dealing with matters relating to inequality and the mistreatment of the less fortunate, it seems completely wild that nobody ever figures out that, in order to be 'protectors of the galaxy', they should probably have some kind of chat with their members about what to do in more morally grey situations.
