” We do not presume people will sin every chance they get.”
we most certainly do!
or at least that they “might” sin
the Tanach, Gemorrah, Midrashim, Mussar Seforim, Rishonim, Achronim, Rabbaim and Gedolim of today, are full of warnings to stay far from temptation. this is the very essence of all gedorim instituted by the Gedolim throughout our history.
mw excellent points
