Well, Clark was alive when Lois died. He could have gone and saved her in the Congo, if he had not been letting Lana tell him to hide his abilities. So yes, at some level, he let Lois die. OK, he had never met her, but still. Some theories are that in canon Clark was traveling around and in some way saved Lois in Congo.
OK, yes I am being too harsh. On the other hand I was just trying to explain why this Clark is so protective of this Lois.
You're blaming alt-Clark for not saving Lois before he knew she existed?

Yeah, I'd say that's a bit harsh.
