Orca TikTok would be a hell of a ride. I'd love to doom scroll the the kid orcas wearing their salmon hats and the adults making reactions videos to their grandkids reviving a dead trend.
Or an orca declaring "I'm Donny Rocksville and this is rock the boat!!" before him and all his friends capsize a ship off of Spain.
Orca behaviour does seem to indicate they inflict pain/misery on other creatures largely for the "fun" of it. But we don't really know, and certainly don't know whether they're capable of properly understanding that their victims are suffering.
I know we don't know for sure but it there is evidence to suggest orcas may have equal or better emotional processing than humans.
In Blackfish one of the most interesting attacks was against a trainer, Ken Peters, who was also a trained diver. The orca seemed to know the limits of the trainer and how long she could keep him underwater. When she brought him up she gave him time to breathe and compose himself before dunking him under again. She could have easily killed him if that was her intent but it didn't seem to be.
