User blog comment:Uknownada/Top 10 Emotional Moments/@comment-3125914-20120630052015/@comment-4754162-20120701005754

One of the more recent very emo'lly powerful scene (by the anime) was after Otohime's assasination before she passed away.

She probably knew who her assassin was (and to a certain extend, I think she knew the incoming bullet due to her strong Kenbunshoku Haki) but still she informed her children NOT to bear hatred for her sake. Also during that pretty emo moment, they need to remember Weak-hoshy cannot climax her emotion (^_^) in fear of unintentionally summoning the Sea Kings. So Manboshi and Ryuboshi had to sing and be happy despite their mother on the verge of death - all this is what I call "for the sake of the greater good". Think about it, at the moment of your sadness you need to be "NOT SAD", its not something that easily done.

While this may not qualify as one of the top 10 (I agree with pretty much all of Nada's above) but just to highlight this part out.
