Giving in to temptation is rarely an isolated, passing mistake. Instead, it triggers a destructive downward spiral, pulling a person toward total physical and spiritual ruin from which it is incredibly difficult to return.
The primary approach among commentators is that the path of temptation leads directly to death and destruction [שטיינזלץ, אבן עזרא]. The exact nature of this downward path is understood in a few ways. It can represent the actual journey of temptation itself [מצודת דוד], the people who choose to follow it [מלבי״ם], or the foundation of ruin that temptation builds [אמרי דעת]. This descent into death happens on two levels. Physically, an obsession with material desires destroys the body. Spiritually, it strips a person of their humanity, lowering them to the level of an animal and bringing ruin to the soul [עמנואל הרומי, אמרי דעת]. Similarly, being seduced by false philosophies or heresy causes a direct spiritual death [מלבי״ם].
As the descent continues, a deeper stage of falling occurs. The ultimate destination is a deep pit, representing a state of ruin that a person can fall into while still alive, finding themselves completely trapped [מלבי״ם]. The connection to this pit is explained in several ways. Some describe it as a matter of proximity, meaning the steps of temptation go so far down that they physically touch the bottom of the pit [רש״י, עמנואל הרומי]. Others view it as a deliberate direction, where temptation aims directly for the pit and drags along anyone who follows [שטיינזלץ]. Another approach sees a more active, sinister relationship. The steps of temptation actively strengthen death, keeping the pit open and ready for the victim to fall inside [רלב״ג, מצודת דוד]. According to this view, even the mere act of walking toward sin, before any actual wrong is committed, is enough to open the pit and trap a person so they cannot escape [מלבי״ם].
On a deeper allegorical level, temptation represents the evil inclination, whose sole purpose is to destroy humanity. Its downward journey is its natural descent into the material world, aiming to cause a righteous person, who is considered truly alive, to stumble and become wicked, which is considered dead. Once it succeeds in causing a person to sin, the evil inclination steps upward to act as an accuser before God. By doing so, it actively maintains the pit of destruction. If there were no sinners in the world, this pit would cease to exist entirely. Therefore, by accusing people and dragging them into ruin, the steps of the evil inclination keep the pit functioning and prevent it from collapsing [אלשיך].
