Cutting to feel alive

This is not an advice for me, but a friend. She does sh and is obsessed with shock content. She does admit liking those contents though her limit is innocent people. She would kill, and i know she would if presented with that opportunity

I think we're all humans and not psychopath because we're constrained by our mind - we're still able to know what is right and wrong (or at least what is normal in society). It is unfortunate that we like what we like, but we cant change that. Even more unfortunate that we even got our hands on these information and making it out safe zone, our personality. But how do you help someone already too deep?

I used to be heavily depressed, does sh and have suicidal thoughts but no where close to her level. I can talk to her, but i want her to see what it's like to be "normal". I can teach her how to fake being one, but that's not the goal.

I don't think she's used to normal content so maybe get her to get used to what she calls cringe (expression of love like hugs and kisses)
