In short: they reveal Dabi has personal motivations for everything he does. Despite his talk about following Stain’s will, and he does, he has personal motivations as opposed to a cold ideology.
He spares a terrified child and it later almost leads to the downfall of the villains’ plans.

He takes time, when he succeeds in snatching the marble, to taunt Shouto in a personal sense.

He takes time to fight Endeavor even though everyone notes how stupid it is to fight him right there, even Dabi himself.

And then the Snatch fight itself isn’t terribly insightful (ti’s cool though) but his comments afterwards are pretty insightful.

In short, he’s motivated by personal connections and emotions. Presumably a bereaved family (likely the Todorokis), a personal grudge against Endeavor, perhaps sympathy for Aoyama, and probably a personal history with Shouto. This undermines Dabi’s claim that his goal is to make the hero killer’s will a reality.

why u lying
It might very well be a philosophy he believes in, but again, I suspect the reason he does is personal (that he’s Touya), because we’ve only ever seen him making decisions from an emotional standpoint rather than a logical one.
