This might sound wild

Is anyone’s actions actually there fault because nature and nurture are the two things that make up one’s personality and those are out of everyone’s control for example is a man steals an old lady’s purse is it truly his fault or if I was born with the same brain as him and possibly same mental disorders and raised the same way he was and both those things would cause me to live the same life he did because everything that he decided was because of how his brain works so if I was born him wouldn’t I too steal the purse from the old lady? So does that mean this action is actually his fault or is it entirely out of his control?
