I think that Suzaku is someone who has done something terrible and is trying to recover himself. I describe him as someone who has created a new personality for himself, and even when he falls down in the execution, he's going to keep playing it until it becomes real.

'Fans' seem to be very unforgiving of his attempts, dismissing them as hypocrisy. However, I'm sure it's becoming clearer and clearer to Suzaku that the world is a complicated place and in order to achieve his ideals, he's going to have to compromise and occaisionally take actions that don't measure up to those ideals.

I think Lelouch wants to be Machiavellian and is failing because he's not as clever as he thinks he is. lol.

However, I think they have both realised that in order to achieve the end, an end that is extremely precious to each of them, life forces you into compromise over the means. The level of discomfort and agonising that reality provokes varies.
