In the Anime/Manga Death Note, do You Think Kira or L is Righteous?

Alright, this is for the fans who have seen/read the entire Death Note series. I want your opinion on Light Yagami, Kira, and L (By “L” I mean the title itself. Not the person- L Lawliet. As in “Near is L” or “Ryuzaki is L”). Then tell me which one you think is more righteous.

Now don’t go saying “You gave me a major spoiler!” in the answers, because I did say ‘this is for the fans who have seen/read the entire Death Note series’.
If you don’t know what Death Note is, I recommend you watch it. Here’s a link to the first Episode in HD.
It’s English Dub so bear with me.

Also: if the person’s real name isn’t stated in the anime/manga, then use their alias instead. Some people don’t know their real names and want to find out on their own. And don’t say “I like L because he’s uber smexy!!!!” for one, we’re talking about the title “L” not the person, and it doesn’t make good statistics if you do that. I want some thinking behind your answers.

So what do you think?
