How do you feel about Asriel as a character? (sorry if you already answered this)
Asriel? Wow I haven’t gotten an Undertale ask in a long time! I never really thought Asriel was a controversial character? Everything he did in life tells me that he was an unambiguously good and kind person, and that everything bad that happened that ultimately resulted in his death was a result of Chara taking advantage of that kindness, and treating him like he was a weak crybaby for objecting to their ideas.
It goes without saying that he was a very different person as Flowey due to being literally devoid of his original soul, but even so he takes responsibility for what he did and apologizes, and that really means a lot.
