What do you think about the killer whale that ate that person at SeaWorld?

It is interesting how people vilify the killer whale for eating a person, yet people eat fish all the time. I believe it is wrong to confine marine life and force them to perform and then when they are too old to perform, you hateful people turn them into fish sticks. If more people had morals, they wouldn't eat marine life or capture them for their sick entertainment needs.
