I look up to Light, that guy is amazing.
But yeah early in the series he's painted as a clear sociopath, which by definition means you shouldn't really relate to him, but you do anyways because he's so cool. I mean, one of the most important things Misa does for the story is show how empty and heartless Light is. Anyone else in his position would've been all over her, but he never thought of her any more than just a tool. Not even a tiny bit.
