third try:
The situation creates the perpetrator by
sudden opportunism.
The situation offers the bad actor the
opportunity to create some grotesque.
Therefore, the bad guy can be displayed
in a realistic manner, and the situation
'forms' the bad guy while being intimate with
the victim.

example:
A suuuper cutsie scene, boy and gurl romantically
walking along the trailways, deeply in love,
making out… love is in the air.

Slowly a train arises on the horizon…

MUUUUHAHAHA, better be quick, boi and then
let's roll it, babe, no need to be shy when just
seconds are left.
