It is a mess, yes, but I don’t think Clarke will kill Bellamy, least of all to make him a ‘hero.’  It is regressive and it is appalling that the Blakes are given morally superior stances that neither have earned and all at the expense of two women who have known better, but the narrative doesn’t want it that way, I guess. There will always be a problem with Skaikru depicted in anyway as heroes as most (save Clarke, Kane and Octavia) see grounders as savage, inferior and have isolated themselves from them and their influence.  Skaikru were always heading in the direction of becoming another Mt. Weather (one of the first comparisons grounders make of them is to the ‘mountain men’), hypocritical and responsible for at least one-thousand grounder deaths since they came to Earth. 

Bellamy’s participation in a massacre, his open murder of two messengers and later, no one seriously calling him into account for it (especially Clarke and Indra who both had deep personal losses as a result – it’s baffling) – is uncomfortably echoed in Octavia turning into an unrepentant ‘assassin’ – almost mockingly taking up her brother’s previous ‘occupation’ and shaming him with it (yet Indra is ‘proud?’ Confounding character reasoning, not much a surprise, really). Killing to give Skaikru an advantage.  Neither deserve to be the ones to deliver ‘justice’ or point out the flaws of those around them.  It’s a painfully dishonest form of storytelling.

I don’t want to guess too much on this (I’m ALWAYS wrong), but Clarke’s shaking gun waving made me think of Titus, having also lost all hope, trying to shoot Clarke to get Lexa to go to war.  Here, Clarke is, as far as we can tell, trying to prevent what could be a mob of angry grounders from getting in and wiping them out (as, if this all holds true, they deserve – and Titus is exonerated as Lexa rolls in her non-existent grave) – but what if the gun goes off and hits someone else?  I’ve been curious why Abby has been so seldom-seen (and whose death might shake Clarke back to her senses?).  

I’ve no evidence for this, just a thought.
