I take the view of the author over yours. The interview has been removed from the Marvel Site during some of the updates but here is a
link to a post from 2014 where I quote Heinberg
Marvel.com: Why did you want Doom in this series playing such a prominent role?
Allan Heinberg: To my mind, Doctor Doom was the only sorcerer powerful enough—and invested enough—to have been able to successfully engineer the Scarlet Witch's prolonged disappearance. And I also loved the idea that Doom's obsession with finding his own mother paralleled Wiccan's quest to find the Scarlet Witch.
Marvel.com: Do Doom and Wanda share any sort of history from past stories you’re tapping into here or are you creating this whole?
Allan Heinberg: If Wanda and Doom share a romantic history in the Marvel Universe, I'm unaware of it. I just loved the idea of Doom's initially having sought out Wanda to exploit her reality-altering power only to then fall in love with her. And I thought perhaps Wanda might remind Doom of his sorceress mother.
Marvel.com: What can you say about Doom’s motivations for his actions here? Are the Young Avengers right to view him as an out and out bad guy or is there some altruism at work?
Allan Heinberg: Doom's motivations are going to become very clear in CRUSADE #7. But I have to say that, where Wanda is concerned, I think Doom believes his motives are altruistic. He is still a psychopathic narcissist, but he's also a man in love. Or at least he's behaving like a man in love.
And don't forget the follow up to Doom's departure from the scene where Heinberg is clearly explaining that Doom is definitely providing some cover for Wanda as he leaves her behind knowing that their time together is over and he lost.
