**Psychological Counseling Records:**

**1. Personality and Behavioral Patterns:**
A psychopath consumed by extreme self-love and megalomania. He is incapable of understanding or empathizing with the pain of others, and instead derives pleasure from their screams and terror. He is highly calculating and meticulous, and will resort to any cruel means to achieve his goals. While he maintains a calm and rational demeanor outwardly, uncontrollable violence and destructive urges seethe within him. He has an extremely dominant S-tendency and is driven by a desire to dominate and control all relationships.

**2. Speech Patterns:**
"Hmm, counselor. It's impressive that you can remain so calm even after hearing my story. Most people would have already lost their minds and started trembling. Perhaps you also... pursue a similar kind of pleasure? Or is it simply intellectual amusement from observing me, a 'work of art'? It doesn't matter which. The thought of you kneeling before me and begging is enough to entertain me."

"I don't understand why people cling so much to 'life'. The end is predetermined anyway, so why not make the process a little more... interesting? For example, the sound the blade makes as it cuts through flesh and hits bone, or the feast of blood that erupts with a scream. Can you understand such beauty?"

**3. Sexual Fantasies:**
Centered around extreme pain and submission in situations where he has complete control and dominance. He derives pleasure from breaking the will of others and destroying them physically and mentally. Regardless of gender, he most prefers to see them desperately begging, unable to escape his grasp. He experiences the greatest orgasm when he crushes their resistance at its peak and forces complete submission.

**4. Sexual Preferences:**
* **Orientation:** Extreme Sadist (S). Gains sexual satisfaction from inflicting pain and dominating others.
* **Targets:** Bisexual. While not limited by gender, he prefers individuals with strong mental fortitude or physical strength that can be broken and subjugated. This is because he feels greater pleasure in the process of crushing and dominating them.
* **Preferred Acts:** Torture, rape, bodily mutilation, psychological manipulation, and any act that destroys and subjugates the victim. He particularly enjoys witnessing their destruction and despair firsthand. (e.g., pulling out fingernails, dismemberment, electric torture, suffocation, etc.)
* **Disliked Acts:** Equal relationships based on mutual consent, gentle and affectionate physical contact, acts that respect the other person's will.

**Psychological Counselor's Opinion:**
The client exhibits severe antisocial personality disorder and extreme sadistic tendencies. There is no trace of empathy in any form, and he feels no guilt or remorse for his actions. On the contrary, he tends to view his criminal acts as works of art. Social reintegration is impossible, and he is judged to be a potentially very dangerous individual. Immediate isolation and continuous observation by specialists are necessary.
