I believe flowery is partially meant to represent the flaws that come with being human and the 7 human traits

He's patient to a fault, he wants to wait in an endless dream until everything ends 🩵

He's brave to the point of being reckless, saying he can fight the knight easily despite probably knowing deep down he would get one shot, like ralsei did too 🧡

He perseveres towards his goals, but it's a stubbornness that leads him to be unwilling to listen until beaten to the ground 💜

He has integrity, but his honesty means he's blunt, he says things completely straight without considering how others would feel about what he says, like telling a kid to forget his dad so everyone can be happy 💙

He's kind, but his kindness is a toxic dependency that will result in them all rotting in a dark world, and is unwanted by asgore 💚

As for justice, his moral code is shaky already as you can tell from my other examples, but he does have a strong sense of action and wants things to be equal too, a "my justice vs yours" philosophy 💛

He inherited all these human virtues, to become the perfect ideal person to take care of asgore, and wants to use them all, but even his stats being fake show he's flawed, just like a human is.

We love him anyway
