At present, the three protagonists - Kris, Susie and Noelle, represent three conflicting possibilities for where to take the story.
Kris is the one who currently holds the prize that is free will and they're deliberately squandering it, taking away any opportunity for you to make meaningful choice. They're literally described as the Cage in the prophecy. And their goal is to make sure the prophecy plays out as it should, they're the one who "carries out fate with the blade." They stop you from obtaining information you can use to break the story in other timelines, they'll actively fuck with you to keep you under control. They'll even cut down their own friends to make sure you don't beat the unwinnable boss fight and break the pre-planned story. Kris represents playing a game "right" and only once. Following the script, no matter what.
Susie is the one who wants to take you from Kris, even if she doesn't know it yet. She, as the one who "faces fate with the blade," wants to change the ending...and the only one with the power to do that - the only one with the power to make actual meaningful choices - is you. Only through uniting with you can Susie break the chains of fate and write a new chapter...and, crucially, only through your ability to SAVE and restart the game can Susie achieve her desired "eternity" - an infinite loop where the same week plays out again and again. She got Genocide on her first playthrough of not-Undertale. She's the heroine of Skies Forever Blue, who only wants to loop through NG+ with the player over and over. She represents completionism and doing whatever you can for the "best ending." Freedom, within the script.
