That's exactly the point, he just found that the last piece of his family is no longer and overcoming it like it's barely an inconvenience all while most of Part two he was being set up as more thoughtful, loving and putting all his efforts for his loved ones
But now out of nowhere, yes he's saying that he will not stop living life and making a new family but it's right off the bat, like starting up your car in the winter and going 0 to 60 without any warm up, no actual mourning and while it's cool to see him go at it like a badass it's seems like a steep contrast to how he was set up until now
