Yes. I think all three, but deliberately phrased things to avoid committing to a meta-ethical framework.

The virtue-ethics and deontological bits are straightforward: "good people don't hurt people without a very good reason", and "don't hurt people [without a good reason]."

The utilitarian case depends how you define utility. But most utilitarians I talk to believe that suffering is bad per se, even if it doesn't have long term consequences. It's wrong to abuse somebody who's dying, even if they'll be dead soon anyway.
