This entire show it's been all about Clarke. She only cares about the few people she loves and herself. When they are no longer of use to them or she sees them as a threat, they are killed as well. Now all of a suden she is this martyr that has to make the hard decisions and everyone forgives her? Lazy writing. She would kill every single living creature in the universe to be with her daughter.
It's been a struggle to watch this last season. If she changes her behaviour entirely in the last episode to sacrifice herself, it's like Hitler saving what's left of the world after burning it to the ground.
