She grew up alone with no friends, poor little thing
I mean, most monsters grow up without friends.
They also get annihilated immediately too, so they don't even get more than a few days of life, nor have a decent amount of remorse or intelligence to develop, since they are mostly made as forces of evil that exist purely to kill their enemies or cause destruction.
She's lucky she is a monster only on the sense that her body was made so she could do her mission (use force to take the hero's belt), not in how she was ideated or treated.
