Ok, my theory is, when you fall down and call out Chara's name, you awaken them from wherever their mind was residing all of this time. When that happens Chara kinda fused with your SOUL, meaning that whenever you gain EXP/LV, that also affects Chara's mind state, therfore: Chara being good/evil is affected by your decisions as a player. There is probably plenty of evidence to prove this theory right/wrong, but, that's my theory. Do with that what you will.
