The infamous "Martha" scene in Batman v. Superman

I'm gonna be the first to tell you that I was a fan of Batman v. Superman (especially when it comes to the Ultimate Edition), but even I will admit the execution of the "Martha" scene was fairly sub-par. But I think people may be hating it for the wrong reasons.

I came across CinemaWins's video concerning Batman v. Superman and his explanation for the Martha scene made me think about it in a new light. Essentially what he said was this:

Batman does not spare Superman because their mothers share the same name. Batman has spent 18 months obsessing over killing this alien who can destroy the Earth. It isn't until Superman uses the name that the alien becomes humanized. At first Batman becomes enraged because he thinks it's another trick. Once he realizes it's Clark's mom's name he starts to understand that maybe they're not so different. He never considered the evil alien had a human mother or let alone would be willing to die for her.

Bruce couldn't save his mother. No matter how many goons he brands, he was a helpless kid when she was killed just like Clark is now. He'll never be able to bring his Martha back. Now he has an opportunity for redemption. It literally has nothing to do with their mother's having the same name, that was just the spark (that you can see snapping Bruce out of his kill-rage) that showed him Superman wasn't pure evil. With potentially his last breath he asked his killer to save someone else.

It's the entire reason we were shown the murder of the Wayne's one more time.

Yeah, I agree the way they wrote it was hammy, but I disagree with the notion that Bruce decided to spare Clark simply because their mothers shared the same name.
