These arguments about determinism versus free will all come down to given a choice between good and evil, some people still choose evil in spite of any all-good ideal. In a determinate world, the choice of evil is not their fault but merely reflects the precursors of their particular life. Given free will, however, it is always possible to choose evil despite an otherwise all-good ideal and so there cannot be a perfectly all-good ideal after all.
We have feelings about things that happen and it is by an irrational unconscious feeling that we choose, not by rational conscious reasoning. Since we can never completely know why we feel the way that we do, we can never precisely know why we choose what we choose. In fact, the essence of free will is in choices that do not have knowable precursors and so are not written in any book of life. The archetypes of free choice and feeling then do not result in any determinate outcomes because neither free choice nor feeling have completely predictable outcomes.
