**Vice → coherence decrease (measurable decoherence signature).**
Distinguish organizational coherence from soul coherence. The criminal organization may be coherent, but the criminal's SOUL is fragmented—constant vigilance against betrayal, suppression of empathy, compartmentalization of conscience. External success masks internal decoherence. The mafioso cannot trust, cannot love freely, cannot rest—these are decoherence signatures. Moreover, criminal organizations eventually collapse (instability), while virtuous institutions (churches, families, universities) persist—a thermodynamic proof of coherence differential.
Pleasure ≠ coherence. Pleasure signals local gradient descent (immediate reward), not global minimum (flourishing). Addiction produces intense pleasure while destroying the person—classic decoherence masked by hedonic signal. True coherence manifests as deep peace, not mere pleasure. The phenomenology of vice includes: post-sin guilt, compulsive repetition, escalation of dose—all decoherence markers. Coherence produces eudaimonia (flourishing); vice produces hedonic spikes amid growing chaos.
The self decoheres. Every sin creates internal contradiction: desire vs. knowledge, action vs. identity, present vs. future self. "Victimless" vice is a myth—the perpetrator is always a victim. Private sin: (a) Fragments the person's integrity, (b) Weakens coupling to the Logos, (c) Creates patterns that inevitably externalize. The "private" alcoholic eventually affects family; the "private" liar eventually misjudges reality. Internal decoherence propagates. Moreover, information is conserved ([[064_BC7_Information-Conservation|BC7]])—sin's decoherence signature is written into the informational structure of reality.
The struggle is not the decoherence—the vice itself is. Paul describes the pre-grace state (Romans 7) before victory (Romans 8). The EXPERIENCE of moral struggle is the tension between coherence-seeking (will toward good) and decoherence (sinful nature). Saints who struggled did so because they perceived the decoherence clearly—that's why it hurt. The impenitent sinner, who doesn't struggle, is MORE decohered—they've lost the coherence sensitivity that makes struggle possible. Struggle is the symptom of attempted re-coherence, not of decoherence itself.
It's BOTH. The theological and physical descriptions are complementary, not competing. God IS the source of coherence (the Logos). Offense against God IS decoherence from the coherence source. The "reduction" is actually an explanation—WHY is sin bad? Because it fragments the soul. WHY does sin separate from God? Because it decouples from the coherence field. The physical description gives content to the theological claim. "Decoherence" is how "offense against God" manifests in the informational structure of reality.
Standard decoherence: Environment-induced destruction of quantum coherence.
Where Kraus operators E_k represent environmental interaction.
Moral decoherence: Sin-induced destruction of soul coherence.
Where V_k represent vicious actions that fragment the soul's density matrix.
Theorem ([[092_T11.2_Vice-As-Decoherence|T11.2]]): For a soul state ψ, vice V_neg(ψ) correlates negatively with Φ:
Or equivalently: Vice acts as a decoherence operator on the soul's Hilbert space.
