Pride can be a good or bad thing. For example, having pride in yourself can help with confidence and self-esteem. On the other hand, having too much pride can lead to ignorance and irrational decisions. Think of some examples from literature to represent this two-sided trait. There are plenty of characters in novels who had just the right amount of bravery and assurance, and the same goes for self-obsessed antagonists, as well.

I think it is because personification is the attribution of a personal nature or human characteristics to something nonhuman, or the representation of an abstract quality in human form.
