I will eternally be a Light Yagami hater

To be fair, I’m an anime-only watcher, so maybe I missed some things in his characterization. I understand the manga adds certain bits of context.

But please help me understand! Why does anyone like or support Light? He is an egomaniac and a narcissist (social media’s favorite buzzword). I disagree strongly with his sense of justice and his moral code. He is disrespectful and unkind, even to his family, and is actively willing to let them die or even kill them. It seemed to me that he did all the crap he did, not for justice, or to create a better world, but because he was obsessed with being godlike, and because it felt nice to be Kira. Much like Walter White of Breaking Bad, who became a meth kingpin not for his family or for the money, as he so often claimed, but because he liked it, because it felt good.

Light Stans, please help me out here. What am I missing. Because as of right now, I literally would put “light yagami is a bitch” on my tombstone, that’s how seriously I hate him.
