I am sure he does think it was worth it, because I don't think he gives a shit about his kids being taken away. He cares to the extent that it makes him look bad (hence his coping and seething), but I don't think he cares because he loves and misses his kids. If he did, he would not be behaving the way he is now. In my opinion, his kids being taken away means no more StReSs from them and their petty little problems, as well as not having to deal with their petty little problems interfering with his literal drug-fueled orgies.
