All this Steins;Gate talk reminds me of the terrible ending in Chaos;Head's A ending.
Rimi kills Taku because she wants Shogun to live, even though Shogun's lifespan was like 1 or 2 days left and Taku could live a normal lifespan. Oh, and Rimi is supposed to be in love with Taku while she makes this decision to kill him. Just wtf's all around.
