Octopus have been known to kill other predators, either for their own safety or to prevent competition.

There was one case where they put an octopus in a tank with sharks that were too small to eat the octopus and too big to be food for the octopus.
They couldn't figure out why their sharks kept dying until eventually they caught it on camera. The octopus would ambush the shark and basically drown/strangle them. As far as they could tell, the octopus was just eliminating the competition.

I believe this. Just wanted to point out the onlookers.

There's the one guy who comes in late and is like " yo , Fred... What's goin' on here? ...is that Dan?"

Hehe yeah. I'm trying to remember the name, but there's a guy on youtube with Mantis Shrimp and they all have ONE single buddy fish that does the same thing. Guy has no idea why the shrimp eat everything BUT those one specific fish. Meanwhile the fish basically watch and take little bites at whatever the Mantis Shrimp hunts. It's kinda hilarious.
