Also Ryuk killed him because the first few episodes he says to Light that he will write down his name in his notebook at one point.
I actually don't know which one I like more. They were both extremely clever. Although I do think that the anime took a turn for the worse when L died, it just lost something which Near nor Mello could achieve.

No he didn't. And if he did light wouldn't have to end up being shot. He failed in the end only because the second Notebook was at N's hands.
