Should Whales be Realeased?

I think whales should because they would get killed in the wild. The whales don't have to have trainers right down at the water with them. they can just be taken care of by sea world or any other place that these whales are at.whales kill its just in there blood, there wild animals no one can change that. I think its unfair to make these whales that have lived in captivity all there lives and make these whales live in the dangerous world. this is why I think they should be kept in captivity but they don't have to have a trainer down at the water with them.
