Not just all 1000 souls of the monsters (which, combined, equals to that of a human's), but also the souls of the other 6 humans: Flowey has to be a "God" to even obtain that form to begin with.

It's possible that Flowey could develop Love, Hope, and Compassion, on his own. If that's true, then I'm sure he don't need our help;  All he wanted us to do is to abandon this game, and move on.
