If there was one thing Yue disagreed with, it was the fourteenth precept, 'Take care for others'. It was no surprise that so little was thought of why people were selfish, why they put themselves first over others. She'd have thought that given his lecture about the evironment, Akimoto-sensei would have stopped and thought about the situation in certain parts of Soul Society and not overall. Because it was impossible to survive in those areas without putting yourself first. Had it been so, Yue would have died 150 years ago in the winter's cold embrace.
