The humpback / orca war?
orca's are quick and they all have teeth.
The humps need to get the spermies on their side.

The 'rescuing' thing seems too anthropomorphic! It suggests the humpbacks view the orcas as 'wrong' and the prey as 'victims' to be 'saved.'
Animals is animals. It'll be food-related like the orcas have an impact on the food stocks preferred by the whales.

Makes me wonder if there is some sort of rivalry... I would think this was just a case of "Driving away prey species," but I just recently learned about "Old Tom."
Old Tom was an Orca whale that actually helped whaling fleets by gripping harpoon ropes with his teeth to help tire out and isolate Humpback whales in exchange for being allowed first picking on the humpback corpse. His skeleton is on display in a museum in Australia and you can see where his teeth were ground down to nubs from repetitive action of gripping whaling ropes with his teeth.
Old Tom, The murder whale.

Orcas are like a lot of predators in that they are opportunistic, and they are smart enough to reason how to take advantage of an easy food source.
I wouldn't call them jerks.
For a major predator, injury is a huge risk. Anything they can do to get an easy meal while reducing risk of injury to themselves is an avenue most predators will take. Few can reason well enough to open quite as many opportunities as Orcas and other cetaceans can, but wrangling something as large as a Humpback presents serious risk to life and limb. Can you blame them for figuring out how to exploit an easier method when it presented?
