I think that making it a character without history removes depth from Flowey/Asriel's characterization and would have made a lot more of his dialogue nearly irrelevant to the Player.

I see Chara as symbolic, honestly. The dust-lust didn't come from nowhere - there is something that precedes it. Creating a novel character in-game that progresses during Frisk's timeline would convey that the Player starts off in game as truly innocent which is... untrue.

Chara's corpse and omnipresence refers to a fall from grace that all humans have had. Even though Chara is pushing up daisies, there is always the seed of hatred and cruelty that waits to be watered. Making Chara the literal "fallen" child is telling.
