Are you kidding? This frog is a living thing. He didn't ask to be kidnapped and housed in your coffee cup! Since you've decided that you will not release him, you at least owe him your best efforts at a good life. Please correct me if I'm wrong, but it sounds like you're saying that it doesn't really matter if he lives or dies. If you don't care about him, why even keep him?! I don't understand your reasoning at all.
