There's a reason why I drew this.

BloodGood may be an asshole to pandora at times, but sometimes he's protective, kind, and caring to her.

Not only that he use to work for her father (unknown at this time), but he's her guardian.

Like a guardian angel

But most likely a dark one who's known as a villian.

And basically, he promised her mother (unknown) that he was going to protect her and her new family.

He's (kinda) attending to keep that promise.
