Honestly, wtf are they doing to her?? Since when would Clarke be okay with letting hundreds of people die for no reason and siding with Jaha over her own mother? This reeks of crappy characterization just to move the plot forward.

They seem to like making characters OOC. (Finn, Bellamy, Clarke, Luna.. )

Clarke's almost always been able to make "the hard decisions" and be practical, but some of her choices lately have been questionable at best. I mean, she was willing to leave herself off the list for the Ark, right? (I think she was.) And now all of a sudden she's hopping into the bunker and shutting others out? I don't buy that.

^ Yep, she was willing to leave herself off the list. Plus, earlier this season, wasn't she also the one letting all the grounders into camp (Luna, Nyko, that child, all the others) while they were rationing supplies and couldn't afford to have more people around/waste medical supplies? So one second she's all 'let's save everyone we can!' and the next second she's like 'fuck everyone else, the lives of these select few matter more.' It makes no sense.

I don't know, honestly.
On the one hand, she seems to me to always put her people first (mt weather, for example. And taking from Luna) but on the other hand, she tries to 'save everyone we can' like sarabeara said. Also, she wanted to take the flame just a few episodes ago to make them all share the bunker...

This show is bad at keeping their characters in character, but Clarke's doesn't seem as OOC as say S3 Bellamy to me.
