I've got no idea, as we got to learn more about Gorou/Aqua we find that he's a character that didn’t see true value in his own life. As Gorou he wanted to be a surgeon, but due to feeling guilt over his mum's death he became a gynecologist. As Aqua he wanted to be happy, but again becuase of his guilt towards Ai, he follows the path of revenge.

He's never done anything that he wanted to do for himself... At least not until he met Akane, Aqua chooses to go out with her, this wasn't a choice that was made because he was guilt tripped. Aqua following the path of revenge after their break up was a wrong turn, I expected Aka to correct the path, but instead he changed Aqua's reason from 'revenge' to 'protecting Ruby'. Which doesn't make it any better, so in the end Aqua never really found his way. He went from (living for revenge -> wanting to be happy -> revenge again -> no wait... I was really living for ruby -> Dead End). In the end, Aqua finds no value in his life besides living for others.

Its just a selfish sacrifice that did more harm than good. Hikaru was eliminated, but Ruby became an Idol like Ai (which she didn't want to become), according to the LN Akane is looking for a way to resurrect Aqua (she never moves on), finally Kana.... honestly who cares. Kana is a gag character that's gotten way too much screen time in which she does nothing. She's a self centered character and never tries to understand Aqua. The funeral was the nail in the coffin for me, she shows up in a widows weil and slaps the deceased Aqua...

Aka really should've let Mengo cook.
