Killer Is Literally Me !! - Tumblr Posts

Why do the killermare siblings still love Nightmare growing up even if he's an asshole?

Because they are in the desperate need, as any other child, to have him.

To have someone to tell them "good job", or to Simply pay attention to whatever they want to say. To tell them how to behave. To care enough to teach them manners, even if they found them annoying.

And before you say anything, yes, there is killer, but he's more of the chill uncle type of man. He tries with all himself to be that Person he personally never had, to his children. He cares for them, but he's not good at conforting people and helping emotionally.

In my au he also as adhd, so he also finds hard a lot of moral things that a parent should know...he never learned how to express his own feelings, so he has a lot to Learn time to time. He also can have mental breakdowns sometimes, so his mental healt isn't the best when they are Little, but as Mercilles goes to Middle school he gets therapy and gets better. AND BECAUSE OF THIS Nightmare is the only adult that knows how to be the one that the kids need.

Nightmare knows how to be in the role of parent, but since he has never been one before, he acts more as the boss, Just like with the bad sanses, but with his children.
