NO! because whales are very friendly. Whales only eat seaweed and small fish. Usually, no. A whale will attack anything if the certain thing is putting itself, the pod, or the young in danger.
It largely depends on the whale. Toothed whales (such as the Sperm and Killer whales) are usually considered to be apex predators. Due to their size and hunting strategies their only main predator is humans (who are usually disregarded from such systems). Baleen whales (such as the Humpback and Blue whales) cannot be considered such as, though they are often protected by their immense size, their young are regularly hunted by other large predators, especially the toothed whales.
Whales are usually bigger, so usually stronger.
Not many predators can kill whales, but small and young whales often fall as victims to killer whales, one of the top predators of the ocean. Humans also hunt whales for their body parts or for food, often illegally.
Whales are mammals. That is they suckle their young.
Usually killer whales kill blue whales.

How many young do gray whales have during their life time
Whales are viviparous, they give birth to live young (unlike fish, most of which lay eggs). Like all mammals, whale calves are nourished with milk from their mothers. The nursing period is long (more than one year in many species), which is associated with a strong bond between mother whales and their young. In most whales, reproductive maturity occurs late, typically at 7 to 10 years. Whales breed seasonally, usually in warm tropical waters and females usually have one calf every 1 - 3 years. The gestation period ranges from 9 - 18 months. Whale calves can swim soon after birth.
