For some reason, L gives me the vibe that he absolutely loved someone. Someone who looked past his quirks and knew he was a good man. Loved him back for who he was, not money or looks. Just a true love. And then, something tragic happens and breaks him...
He was strange his entire life due to his posture and his actions, but he was a genius. A good man trying to catch a bad man. (He didn't deserve to die in my opinion. ;-;) And that's why his significant other loved him for himself, he was a great character.
I know alot of people have their opinions on Kira and all, but to be honest, I was against Light from the beginning. I undestand he wanted justice, but one person cannot change the world humanity does. It wasn't the way of a Salvation for Light, like he thought, it was his Damnation in a way. Ryuk was going to kill him in the end and criminal activity would rise once more. There are going to be criminals in the world. And Light went too far trying to be the god of the renewed world.
Sry for this big post just i like expressing myself
