When the whole Tournament of Power arc began, I was thinking what a shame it was that we didn't have any villains around anymore. The Tournament of Power isn't a simple friendly competition. Everyone's very existence is at stake. It would have made sense for heroes and villains to join forces to save the Universe they inhabit.
So I don't mind that Freezer will join the Tournament to defend Universe 7. But I admit I am annoyed by the fact that the character keeps getting killed and being brought back. Though in the world of Dragon Ball, I guess we should already be used to it by now, that characters won't ever stay dead. Certain Z fighters have already died multiple times and were always brought back by the Dragon Balls. And hey, this time it's only going to be for 24 hours, before he has to return to hell.
