Yes, we should instead look to have Justin Bieber or Twilight fans perish in natural disasters.
If it was Justin Bieber themed only the Justin Bieber fans wouldn't perish.
Would you download a Justin Bieber natural disaster app? If the answer is yes then this conversation is over.
If it were the only option, yes. Wouldn't you?
I think Bieber is a twat. But you're almost making putting his face on a disaster app sound like a good idea. If we're accepting selecting people based on their traits and biases, those who are unable to put aside a petty dislike for a pop star to survive seem like a decent place to start.
