The answer to the original question here is that there is on question that a man has a Yetzer Hara, a Ta’ava. In fact, a man has a bigger one than women. Reb Meir, having learned and broken his nature, reached a level where, as the Chovos Halevavos writes, the Yetzer Hara left him. This is what the Gemara refers to as, Libi Chalal Bekirbi. That being the case, he couldn’t even undertand the concept of battling with the earthly desires, and so he mocked Ba’alei Ta’ava as if they are being manipulated by little force. Therefore, the Sattan came to show him its full force, and that if not for his Torah, Torah Tavlin, he wouldn’t naturally overcome his inborn nature. Hashem made the system that it can be overcome, but don’t think it happens by itself.
Da’aton Kalos, as mod80 said earlier, means that they can be won over. That is why Rabban Shimon bar Yochai was afraid that the Romans would somehow convince his wife to divulge his whereabouts. This Talmid proved to her that she can be convinced, which embarrassed her immensely.
