Season 3 would've been a near perfect "end" to the series
While having Joe receive his karma in the final season was very satisfying, its callbacks to previous seasons, and THE due justice for Beck (dare I say also, Peach?). I find that the end of Season 3 would've been such a perfect and imo "realistic" ending to the show. Love is entirely blamed and despised by everyone in the community, meanwhile Joe is presumably "dead" to everyone and free of any scrutiny. He even gets some version of a "heroic" ending, as he's the one to stop Love's murderous tirade and even leaving Henry to be cared for by another family with hope that a normal life prevents him from becoming like Joe/Love.
It really reflects how in the real world there are so many "Joes" that lurk around hurting others and never truly are held accountable for their actions. With that sometimes the justice for their victims is never actually reached either. While Love isn't innocent by any means, her being the only one punished really adds to this narrative that the female characters presented in You are always the ones who have to face the most ridicule/harsh endings for their actions by comparison to their male counterparts who do equally worse.
