No, it's fine. At the end of the day, they aren't sentient. They don't have emotions, they can't think, they don't enjoy life as we do. Killing them makes no difference, not even to them really. And don' forget, they wouldn't hesitate to kill you if they could.
That said, they should be killed quickly. Deliberately inflicting pain, while not only immoral, is an indication of a sick mind, and I don't tend to agree with killing them just for fun. A quick kill doesn't faze me at all, but seeing them wriggle and having to finish them off does disturb me a little.
