worst thing i've done is probably be with a prostitute that i didn't check entirely was not being trafficked... i did ask, and was reassured she was independent and okay in life, but i had/have not really done that so im not sure if i was fooled. the guilt gets to me a lot even years later if i have contributed to any evil people's pockets/helped to hurt anyone. obviously, i dont see prostitutes at all anymore, i was at a low point in my life.
i asked this question once to an ex while on acid, and she hit me with a suprising response. still dont know if she was messing with me, but she stuck to the story for 6 entire months until i told my grandpa in front of her, but she told me her ex bf with ms13 when she was 15 had kidnapped, tortured (cut off his fingers one by one while he prayed for his life), and murdered someone who had raped her as a child (her friends father), melted his body down in some acid and fed the remains to catfish. shit hit me off guard, i was like wtf.
not to mention this ex was missing for 4 years when i met her, and i verified that :-/ she was worried the gangs were after her because he snitched about some shit, had me looking over my shoulder and paranoid for years
