My friend has a pedophilic disorder

Uhm it's a long story (⁠･ั⁠ω⁠･ั⁠) My friend was a really nice guy when I first met him but as time went by, he met new friends and ofcourse I was so dang happy because oh boi that guy is a very closeted person but soon when I checked his channel he posted a sh0t4c0n manga 🕴️ with a caption that says, "Woah my friend gave me this." It was WEIIRRRDD and he started to like Instagram posts that came from l0l1c0n accounts and when I confronted it to him he just said "yeah okay" (⁠〒⁠﹏⁠〒⁠)
