Sin

Sin leads to shame and guilt, which can result in self-loathing and hatred. This hatred is a willing of evil for the self, the root of despair. Repentance is the will moving towards its good, which is God who is Love, and away from sin. Self hate arrests this movement. So sin traps the soul, preventing us from moving to God, or even accepting love from Him and others, and ultimately bringing us to self-destruction.
