The difference between Light and Lelouch is that Light regretted his life when he died while Lelouch died with satisfication. Towards the end in Death Note, you see Light recounting his memories about how he acquired his Death Note, L, and (this is only my opinion) even regretting using the Death Note. However, Lelouch died knowing that the world can continue in peace without him.
