Well, he sure is a psychopath and manipulative. But, i saw a glimpse of character development from him the moment he knew and bonded with their kids. Like when he recalled how his mother show affection to him, and tried to do it with Leanne and Enril (the head pat scene? Yep < 3).
Also as he tuck the kids to bed and change his mind from using them to bait Elan, to just wishing a happy family life with all of them together.
He may not be a great lover, but he sure is a great dad. And i love him for that. I hope his character development will steadily bloom in the future chapters. And please, talk to Elan like a normal person would. Have some healthy communication a'right?
