Could you perhaps be more specific? I'm kinda not seeing exactly what you're talking about. Once he finds out where Nunnally is, tries to rescue her, and freaks out after he fails, he leaves Japan so he doesn't have to fight her anymore. He doesn't put Nunnally and Ashford into danger until the second battle of Tokyo, at which point he puts them both into a ridiculous amount of danger for what seems to be not that great of a reason. Honestly, even though Lelouch is a brilliant guy, he does really stupid things sometimes. "I could even make you kill all the Japanese if I wanted to!" Or when he sends Rolo after Nunnally knowing fully about Shirley. And if you want to talk about not learning from his mistakes, how long did it take him to do ANYTHING about the Lancelot, which showed up EVERY TIME in battle? Then he walked up to Suzaku and got taken hostage. A gun is a long range weapon, he didn't need to get that close.
