what happened to the original plot of the movie

in the end eren passed down the blame and the guilt to two girls: mikasa and historia. he basically chained one girl and sacrificed the other. it’s just not like him to do that :/

no im mad fr cause wbk eren is a hypocrite but the ONE thing he was consistent in since timeskip was refusing to sacrifice historia. mappa even added an anime original scene emphasizing that. but in the end he let her marry her bully for a plan and dumped all his sins on her
