A question for you *UPDATED*

Here’s a question:  Is it immoral to wish for someone’s death?  I’m just talking about wishing, rather than doing anything that would in any way hasten the other person’s death.  But can a moral person ever wish, really hard, for another person to die?

UPDATE:  On the subject of wishing for deaths, I do consider this type of thing immoral.  Although it does nothing to advance a person’s death, it nevertheless can cause great pain for friends and family who are unaware that a cruel joke is being played on them.
