some girls with tats just love the art. well adjusted, just love how it looks and that they're unique.
some with tats are trying to prove themselves... same personality that has to post 50 motivational phrases each day or post how someone wronged her, so that a bunch of swinging dicks will tell her how awesome she is.
like everything from skydiving to professional bodybuilding... some people are normal, some are screwed in the head.
