Gentle Giantesses

Is a woman who suddenly becomes an unstoppable giantess more likely to be a gentle giantess who tries to help little people or an evil one who thinks of people as nothing more than her toys who are to used in whatever way she desires.

Alot of giantess stories/interactives tend to favour the evil giantess scenario. It could down to what she was like before the growth but some turn evil upon growing so what is the more likely one? Good or Evil.
