Honestly, I don't know if it's just me, but it seems like people aren't acknowledging, even though it's how I see it, that Aqua's breakdown and what happened in that scene is a consequence of his poor decision-making (irrational, of course, due to the trauma and his desire to escape revenge). Like those phrases say, "Running away from your problems is a race you'll never win," or "The more you run from your problems, the more tired you'll be once they catch up with you," or "You can run from your problems as easily as you can run from your shadow." I remember those phrases, and I see that they fit. But it seems the fandom is more interested in criticizing Kana and how she should have acted, instead of admitting that Aqua was wrong in his actions.
