So was the Brotherhood stuff, and the creepy make Wanda dance stuff that became a meme. But it really doesn't matter. Knowing or not knowing doesn't make it acceptable and still makes it a red flag and character flaw. Him being their father just made it more creepy later.
In the panels of that situation, it was completely to get Wanda and Pietro back in the Brotherhood and not to get her out of a catatonic state. Nor save Wonderman. That incidentally happening doesn't give him the credit, because that was clearly not his intention.
