Minato is quiet for a few moments at that, looking sidelong at Domon before sighing.

"Maybe I shouldn't have. Or maybe the end still would have been the same. It doesn't really matter, except maybe as a lesson for what to do next time."

It seems clear that there will probably keep being next times, every time the moon is full. It's not that Minato blames Domon or anything - but he thinks that since it's a predictable cycle, maybe they can set up precautionary measures.
