VILLAIN! or not?

The birth of a child after years of trying and miscarriages, they both decide to be wonderful parents to this child, give her the life they never had, as she opened her eyes shock bestowed upon them, there was no light, no happiness, her eyes were dull blue almost as if she were not alive
beware of mentions of triggering topics such as gore, child abuse, etc

Would you pity a person who chose to be a monster despite given a chance to change?
