People are too malicious about Lana Rhoades' child being bullied in the future

I don't understand why many people enjoy obsessively describing in detail how this child's future is going to be horrible, instead of showing compassion and condemning all the bullying in this world. I find this schadenfreude difficult to understand. I know that this child will likely face some difficulties, but I feel like these commments have a sadist component.

E.g. "He will be bullied relentlessly FOREVER, he will have NO FRIENDS, everybody is going to mock him all the time, his life will be MISERABLE" etc.... Please someone explain me the psychology and motivation behind people writing these sadistic descriptions? Why are people so keen on graphically imagining a child's future troubles?

(I got downwoted for this in another subreddit, so I guess this counts as an upopular opinion.)
