i have known this person on discord for a few months now. he types in some version of the uwu language that's really hard to understand and he is super over the top and aggressively affectionate. he likes to roleplay a lot involving a lot hugs, kisses, gore, hard and soft vore, digestion, and scat. he claims to have some sort of learning disability and mind reversal fragmentation.
this is the part where it gets problematic. he has a hard time respecting other people's boundaries. he has stated a desire to torture me. he said he wanted to kill his parents but he won't because there's so many other that should come first. he's claimed to have tortured cats. he told a story about how a cat died and how happy he was that his brother was sad about it. he's asked me to torture cats. he's asked me to record me hurting myself. he's stated a desire to kill me and not his parents because he loves me and not his parents. he's stated a desire his parents would die so he could take their inheritance. he has some sort of master plan and idk what it is, but he told me i can help by him drinking blood, me hurting myself, torturing animals, or engaging in sexual acts with him to recover his mind. he has frequently tried to be sexual with me, despite me telling him to stop. he is 17 and i'm 20 btw. when asked how he would feel if someone tortured him, he said he would scream, cry, and suffer, but ultimately it would be good because torturing things is good. he's claimed to have watched other people self harm on discord, including a suicidal person almost attempting suicide.
i really want to help him out and i know i can't fix him; i just want to know how i can be supportive. whenever i ask questions or suggest therapy he views me as some sort of outsider and whenever i send him pictures of me being injured he views me as a true friend. i don't want people telling me i need to leave him or block him. i will not abandon my friend. how can i be supportive and help manage his conditions while still being his friend?
