It's been DECADES. What was he doing for the last 20 years? This is ridiculous. He wasn't being introspective, he's xenophobic. If I say all people of a certain nationality or country of origin are default untrustworthy until I can personally verify that they are loyal, I'm not being introspective, I'm being xenophobic. That is what Sam Lane has been portrayed as for the last 20 years. He's not being reasonable. He's paranoid and doesn't trust people. That is what he himself admits. That's not meant to be portrayed as a good thing. That is a character fault.
Sam's coming around isn't validation of his viewpoint. He's admitting to Lois and himself that he needed to change and open up. She admitted she herself has to open up to him first on the hope that it would get him to see he can trust people. You're completely missing the point of this whole arc because you want to vilify Lois. He's not "verifying" Clark or Superman are ok, if that was the issue he literally could have done that at any point in the past. He's not even doing that now. He's not applying the same standards here. What he is doing is for the first time he's trusting Lois and opening himself up to others. That's the scene where he goes back to Lois' hotel to talk to her after she tells him about Clark. That's the whole point of that scene. That's his arc here.
Decades later! After finding out his grandson is an alien!Both have trust issues. Yes, but lois didn't put aside her pro-superman bias. Sam was willing to here out the other side.
I don't think that is the take away from Superman. But even if it was, it has been decades since Superman appeared in this universe. Come on man. This isn't a few months after he first appears, it's been like 15-20 years. You're being completely disingenuous here.Has lois ever given a thought if superman was a bad thing and concept to the world?
He alienated her and her sister for years. He admits as much. His inability to trust people isn't a good thing. It's pathological. He acknowledges this. He acknowledges he was wrong. He wants to change and is willing to try to change so he can open up to Lois, Clark, and Jon. He implies as much to Amanda Waller and explicitly states this to Lois. He's not blameless in this because he created the environment where she felt she had to hide things from him over the years.Lois is the one who treats sam badly. Not the other way around. so she is terrible.
None of this is binary. Literally none.And its not even consistent.you can say its grey. I don't feel it is. I didn't start this. I was merely pointing out the double standards of the characters in question. Clois(regarding their decision. Because decisions are binary. Either you do something or you don't ) and jor el. It's like saying harley quinn is a grey character. She ain't. Jason todd is grey character. Batman is grey. Heck! Lex can be grey.
