Probably not a popular opinion but I respect DM for taking over the concern for the children as if they were his own, given there’s no communication from the mom. He hasn’t criticized her in the slightest, nor distanced or removed himself from taking responsibility over the children as some partners of women with young children might tend to do.
How easy would it be say “I always warned her about letting those kids run around and look what happened” or “They were her kids, I didn’t have much to do with them, I was usually outside”.
