John's Humanity

The concept of love is based on a basic instinct to reproduce.

This basic instinct is preserved through a belief in a higher power.

[this is to mean intentional instinctual survival, such as avoidance of suicide, rather than an animal's innate desire to survive without a deep conscious reasoning behind why - although, even this is faulty, for within suicidal attempts one still encounters instinctual 'fight or flight' responses, and conscious intention does not easily override these]

Acting in contrast to this basic instinct is primarily what makes humans unique.
