My brother left my disabeled mother to die in a diaper after a fall, until her leg turned septic from an untreated fracture. He was legally in charge of her and my dementia addled father; put a DNI on her and let her die of a heart attack after sitting in her shit for a week.

Then promised to fly me out to the funeral and ghosted me the same week, leaving my maternal family thinking I skipped the funeral.

Secondhand experience was being a content moderator for Tiktok and witnessing every warcrime, csam or otherwise horrible video spread on the internet for internet points before we had to manually flag it and take it down.
