Indeed. It also needs to be remembered that it's no sign of strength to be able to make excuses for one's actions, no matter how low and vile. A strong person who knows he must do what needs to be done to achieve a greater purpose can do low things knowing fully well just how low those things were. He doesn't need to twist the truth and try to explain this and that, trying to make it sound perfectly honourable to himself. It's a different thing what should be told to his underlings, though. It could very well be much better if they don't think any compromises had to be made. And that's what happened.
Like shinta|hikari suggested in his last paragraph, I also will like Lelouch much more as long as he knows, himself, that he must accept sacrifices and ill deeds in order to gain greater victories. If he at some point begins to believe everything he does is automatically right, like Light, then some part of me is going to start to hope for his defeat.
