A Story of Addiction
Vayar ossah - Shechem didn't guard his eyes, he saw her,
Vayikach ossah - he took her, [just a little bit...]
Vayishkav ossah - a fall (normally)
Vaya'anehah - out of control (abnormally),
Vatidbak nafsho - he became attached = addicted,
Vayehav ess hana'arah - he convinced himself that it is just regular love,
DENIAL: He asked his father to take her for him as a wife. [As if all is in proper order]
WHAT HAPPENED IN THE END WITH 'GOING AFTER HIS EYES'?
IT DIDN'T END UNTIL HE AND HIS WHOLE CITY WAS DEAD.
