childhood trauma such as sexual harassment or violence can have an impact on paraphilic disorders and that is what Desta experienced

Desta is often harassed by people around him, he is an orphan and has never received the slightest love from his parents

You see Desta being bullied, stepped on, grabbed until he's bleeding. You helped him and chased the bullies away. Instead of thanking you, he's angry at you

"What are you doing? I need their torment right now!!”
