Tragedy at Sea World

So just recently during a killer whale show, which in itself sounds bad, a Sea World trainer was killed by a whale. First of all it's so sad because ever since she, the trainer, was a little girl she said that this was what she wanted to do. And for the whale she had been working with for some time to snap like that is tragic. That whale had killed people before though. There was a case when a person snuck into Sea World and they found the person dead on top of the whale. Why was the whale still in the show and so close with people when he has killed before?! I don't understand. What I do understand is that it was probably only following it's own instincts because after all it is a "killer" whale. I'm kind of torn about what I think they should do with the whale now. I know they aren't going to kill it which I do think is fair because he was only doing what his kind do. But should they release it back into the wild? Or would it die because it's been a different setting for so long? I mean I'd assume if it can still kill a person, awful to even say, it could kill some krill or whatever kind of fish they eat. It's a sticky situation. I'm an animal lover but some animals are not meant to be domesticated or even in shows for that matter! BUT I read that they aren't secluding him from the other whales because he fathered some and so he can still mate with other whales. And that he'll still be in shows but they are going to review the ways they work with him. I don't know. Doesn't seem like such a good idea to me. I guess we'll see what happens && just hope he doesn't kill again.


EDIT: I just found out that it was not the whale's fault! The trainers ponytail got into the water and the whale was intrigued by it and was really just playing with her. Too roughly but it was the trainer's error and not the whale's fault. I feel bad now :( but people need to be more careful with certain animals.
