Is NOBODY wrong in the post ? POST : I haven't done it yet, notice the WIB in WIBTA.

I am 21 M (not sure if it is relevant), and the friend in question is 21 F. Well, I call her a friend because everyone in our circle pretends so, but I have so so many grudges with her for bullying me plenty as I was growing up. Her dad used to bully me as well. Now obviously, I didn't know it was bullying back then as anti-bullying campaigns hadn't taken off. But i realized it in retrospect.

Now, fast forward to yesterday, a friend of mine who used to date her got dumped by her and in a drunk outrage showed us some pics and videos on his phone of her injecting and inhaling illegal stuff and flexing on her stash of them as well. In a couple of them, she also yelled out some anti-semitic Nazi sympathizing and racist stuff against blacks and muslim immigrants (wasn't a surprise for those who knew her personally). There are videos of her doing the preceding things naked as well. And when we were drunk, I asked him nonchalantly if he could share them with me and now I have them as well.

I am contemplating whether to send it to her dad and to the head of police department in my area. She, thanks to her dad's influence, got into a prestigious German Uni and I am contemplating sending it to them as well. In short, I now hold the key to her demise.

I don't think I'd be an asshole at all, because apart from my personal grudges, for which I was never able to take revenge (thanks to our mom becoming friends), what she did was illegal. And her dad deserves to get punished for it as well because his reason for bullying other kids, including me (and he still does it) was that they were not well behaved. How dare one does that if they were never able to teach their own kids how to behave?

But my moral compass isn't flawless. Yesterday, my girlfriend asked me to ask myself a rhetorical question, since the reasons I was giving her was being a responsible guy who wanted to keep the streets clean. The question being would I have done the same if it was somebody else, perhaps a stranger? The answer is a shameful "no". So, I think I have a problem.

Thus, I would be glad if you could pass a two-fold judgement.

WIBTA for going ahead with this?

AITA for not even contemplating doing this if it were somebody else?
