Like all animals, they have a vital role to maintain not only the oceans ecosystem but as well for humans. If the whales die then there would be too much krill in the ocean which could effect biodiversity of the oceans. As well whale poo helps underwater plants to photosynthesis CO2 into Oxygen. If the whales die then the oceans will die and if the oceans die then we will die as we cannot live with a dead ocean.

As well there are moral and ethical reasons for not to kill whales.
