Gemara Shabbos 20a and in other locations mentions כמאכל בן דרוסאי Rashi explains that Ben Drosai was a thief who ate his food when it was only cooked 1/3. Did Ben Drosai have some sort of Zechus that his name is often mentioned when it comes to Halchaos of Bishul on Shabbos?
According to our Maggid Shiur, the Talmud Yerushalmi claims that Ben Drosai sinned by worshiping idols.
In order to repent, he decided to start stealing from Avoda Zara; thus becoming a "hero" of a thief.
I cannot find any reference to this story by searching the Yerushalmi, though.
