I don't really think Lelouch was morally bankrupt. I mean, he made some nasty decisions, but his situation was also a lot different (Light lived in modern Japan, Lelouch lived under a regime that officially endorsed racism and discrimination), and his intentions were always to carry out his plans for the sake of others.
Anyway, ANIME.
Uh, watch Haruhi. Even if you don't like it, at least you will understand the internet that much better.
Also, watch Clannad, it is a harem, but it's pretty wtfpwn.
And I guess from what you like I could recommend Durarara!! as well.
THAT'S IT FOR NOW.
