Feature	ASPD (Antisocial Personality Disorder)	Narcissistic traits	Avoidant attachment
Core issue	Low empathy + rule-breaking tendencies	Self-worth regulation through admiration	Fear of emotional dependence
Capacity for love	Can form attachment, but often conditional or self-focused	Can feel attachment, but often tied to ego/validation	Can feel love, but struggles to express/maintain closeness
Empathy	Often significantly reduced	Variable, often selective	Generally intact but emotionally suppressed
How they bond	Control, utility, loyalty, habit	Admiration, idealisation, validation	Distance + safety + independence
Reaction to intimacy	May become controlling, detached, or inconsistent	May idealise then devalue	Pulls away when closeness increases
Emotion style	More shallow affect or reactive emotions	Emotional reactivity tied to ego threat	Emotionally restrained, self-contained
Stability in relationships	Often unstable or instrumental	Cycles of idealisation/devaluation	Stable if space is respected, but emotionally distant

🧬 Key neuroscience/psychology takeaway

• ASPD: bonding systems exist, but empathy and moral-emotional regulation are reduced → attachment can be real but not deeply reciprocal in the usual sense.
• Narcissistic traits: emotional systems are intact, but self-esteem regulation dominates relationships → love becomes conditional on validation.
• Avoidant attachment: emotional capacity is usually intact, but the brain downregulates closeness responses due to learned safety strategies → love exists, but is suppressed or limited in expression.

💡 Simple way to remember

• ASPD = “connection without empathy constraint”
• Narcissism = “connection through ego needs”
• Avoidant = “connection with emotional distance”
