David, the Torah’s view (and by that I mean the Gemara and rishonim etc.)is that a person should never put himself in a situation where he may fall to the yetzer hora (“the demons within us” as you put it so well. Made me smile:). An example of this is the famous story of Dovid Hamelech and bas sheva. The medrash says that Dovid actually ASKED to be tested by Hashem, so that he could rise to a higher level ( and be mentioned with the avos in shemona esray). As we all know, sadly Dovid fell to the yetzer hora, and many bad things happened as a result. Our sages conclude that the moral here is never to put yourself in a situation where you can fall, rather play it safe, and don’t try anything fancy.
While your opinion is a reasonable one, (Dovid Hamelech had the same idea after all!) it is not the Torah’s opinion, and therefore not the way a Torah Jew is supposed to act.
